Quantified Self: Metabolic Efficiency Test

I’ve wanted to do metabolic efficiency testing for a long time. I think you can play around with your nutrition and really dial it in, but it’s always nice to have some more exact measurements to better define and guide your own n=1 experiments. I personally just like to look at data, and if anything, use it as a learning experience and a form of continuing education for myself.

Endurance PTC is really the closest place around that has the equipment for a Metabolic Efficiency Test (MET). This past week, I drove to Mill Valley for a couple hours of testing with them. Here are the results of those tests.

Body Composition

The first thing I did with Tim at Endurance PTC was a body composition test. I thought this was going to be a little more scientific, but it’s really just the old-school skin caliper test. He tested my skin fold thickness at 3 different spots on my body (multiple readings at the same locations): belly, thigh, and ribs. The results, 12.5% body fat. That’s a bit higher than my Withings scale tells me every day (it says 8.5%). I secretly wanted to be under 10%, but I’m not sure if these numbers actually have any meaning for me in terms of performance. I don’t think you can say that if you went from 12% body fat to 10%, you will be a better athlete. In general, it seems better to be lower, but for me, it may not be the case. I think the more important thing here is to track changes and not the value itself. I don’t anticipate going in and doing skin caliper tests often, so I don’t think this was a super insightful test outside of reminding me I need to be aware of all the dessert I enjoy so much.

Sweat Test

Endurance PTC also offers Precision Hydration sweat tests. I thought this would be very applicable to my performance as I’ve always struggled with hydration due to my extreme sweat rate. The more I understand about sweat rate and sodium depletion, they better endurance athlete I think I can be. I really feel like a major limiting factor in my training and racing is the amount of fluid I lose from sweat.

The Precision Hydration sweat tests are pretty interesting. They put 2 quarter-size disks on your forearm with a chemical on them that makes that part of your skin sweat. Then they add an electric current, which you can’t really feel, to that disc to push the chemical into your skin to start the sweating on that area. Then they remove the discs, and collect the sweat on your skin and run that sweat through a machine which analyzes the sodium content of the sweat. You can see the process here. The idea is that the sodium content of your sweat does not vary much as your sweat rate increases or decreases. You always lose about the same amount of sodium per volume unit of sweat across all different sweat rates.

I had done the Levelen sweat test previously, which seems much less accurate, and had put my sodium loss at 1400mg per Liter of sweat. This Precision Hydration sweat test put my sodium loss at 1024mg per Liter of sweat. So this looks like I lose a little less sodium than I previously thought. This may explain why I looked like a bloated pig after my last race. Good to know. Now I can better plan my sodium intake during long training days and races.sweattest

Metabolic Testing

The last, and most time consuming test, was the Metabolic Efficiency Test. Tim at Endurance PTC looked me up to the Respiratory Gas Exchange system while on a stationary bike. This machine measures the amount of Oxygen I breathe in and the amount of CO2 I breathe out while riding the bike. The ratio of CO2 eliminated to O2 consumed is the Respiratory Quotient (RQ). This is a way to measure metabolism to see what I’m “burning” at different exercise intensities. An RQ of 1 is pure carbohydrate (sugar) metabolism, where a RQ of .7 is pure fat metabolism. My goal was to see how much fat and carbohydrate I burn when I am out riding. The ultimate goal here is to train your body through nutrition and training to be better at burning fat and to burn more fat at higher intensities.IMG_3060

The test was designed to start me at 120 watts on the bike and step me up by 20 watts every 5 minutes until 240 watts. This would give me a range of sub-max power outputs on the bike applicable to the types of races I do. I will say, it’s pretty uncomfortable to have your nose pinned and breath through a tube on a trainer up to 240 watts. Very do-able, but very awkward. IMG_3061

Here are the results:


I was secretly worried that I was a huge sugar burner. Most people who know me, know I have no concept of moderation when it comes to dessert. So, while I’m pretty picky about the quality of the dessert, I pretty much will demolish all sugar put in front of me (especially if it’s homemade with love). So I was pleasantly happy that I was still able to burn a good amount of fat at higher intensities.

My cross over point, where I burn equal sugar and fat is around 210-215 watts. This is about Ironman pacing on the bike.

My Fatmax point, where I am the best fat burner (if I wanted to burn lots of fat) is 160 watts, which is pedaling fairly easy. So if I wanted to burn off all that ice cream which converted to fat, I’d be better off going out and doing a very easy bike ride than going out and doing a hard ride.

I think this data is going to be very useful for planning out my nutrition strategy for long races, like Ironman. I think I can probably get away with consuming less calories from sugar than I previously thought, looking at this data.

Another interesting take away is that my Metabolic Efficiency Zone, where I am the most metabolic efficient (more fat burning) is 140-180 watts. In theory, I should be spending a lot of time in this zone training, where I would be “teaching” my body to be a better and more efficient fat burner. The reality is I never train this low on the bike. So maybe I need to slow down my easy rides. This also probably means, I should slow down my easy endurance runs, as I assume this data would translate over to running as well.

Overall, I got a lot of good data from these tests and I’m glad I did it. I think this data will guide more trial and error testing on my own in terms of training and nutrition.

Ironman Hawaii Hydration and Sodium Planning

With a high sweat rate comes challenges with athletic activity an athletic performance that I am all too familiar with. When it’s a hot day out and I have a workout, I usually fall apart. All of my worst training days have been when it’s hot out. I can easily lose 10+ pounds of weight during a long run or bike ride if I don’t pay attention and plan my hydration needs.

This has become more of a front and center issue in the last couple years after choosing to start Ironman racing and training. For shorter distances, sweat loss can be managed without too much thought. With the long distances, I really needed to make sure I understood how to manage water loss and dehydration for both training and racing. I have been lucky up till now that all of my Ironman events have been in relatively cooler weather. Training in Monterey County also tends itself to mostly cooler weather, especially in the early morning or later afternoon, when I tend to do the majority of my training. When I qualified for Kona, I knew I would have to take a serious approach to understanding my sweating “problem” and my overall hydration needs for hot weather racing. I knew I couldn’t just cross my fingers and hope for a cool day in Kona… it wasn’t going to happen.

My first step was to quantify my sweat rate. This is very easy to do. I simply weighed myself before and after workouts, and also weighed all the fluids I consumed during my workouts. I could calculate total weight loss over the length of my run and bike ride and account that for sweat lost during the activity. I started doing this in August, leading up to Ironman Kona for key workouts (typically on hotter days). I also recorded the average temperature during the workout and also my average pace or power for the workout. My hope was to correlate a sweat rate to a temperature and to an effort level. With this, I could approximate my sweat rate for a given effort level and air temperature.

Here is a sample of the data I collected for my bike rides:

bike sweat rate

From the above, you can see that 1.5 L/hr was a rough idea of my sweat rate on the bike. The last entry is actually my Ironman Kona Race Rehearsal, so the power would be close to race day. You can see I lost over 16 lbs of sweat on that ride, and it was under 70 degrees out. That’s a lot of sweat! I nailed the hydration though, because I lost no weight at all on the ride.

Of course, I really didn’t hit any temperatures which would accurately represent the heat I would get in Kona. I was lucky to see some unusually high temps for Monterey, but that still wasn’t enough. I wonder if there is a maximum sweat rate at which you really can’t sweat any more. I imagine, at some point I would hit my maximum sweat rate and temperatures above a certain point wouldn’t matter as I wouldn’t sweat any more.

Here is a sample of the data I collected for my runs:

run sweat rate

From the above, you can see I can easily hit 3 L/hr sweat rate when it began to heat up above 80 degrees. To me, this was most disturbing part of my findings. 3 L/hr is a ton of sweat. There is no way I can drink anywhere close to 3 L/hr while running.

During this time of testing, I was also doing sauna heat acclimatization where I would sit in a dry sauna for 15-45 minutes 3-4 days a week to prepare for the Kona heat. Heat acclimatization increases blood plasma and also increases ones sweat rate and affects how quickly they begin to sweat. I could see the affects of this in the data as my sweat rate did seem to increase per temperature/pace over time. I’m still not sure if this is a great strategy for me. Given that I already sweat more than most, I’m not sure I want to make my body sweat even more. I’m not sure that extra sweat means more cooling or if it just means I can dehydrate that much easier. I’m still not sure heat acclimatization works for me and my situation, where I already have a very high sweat rate at baseline. I need to do some more research on this to see what is best for me next time.

I also did the same testing for swimming, but I noticed I didn’t really lose any weight swimming. The only weight I lost swimming was actually due to going pee (yes I get out of the pool or wait till after the workout) and not due to any sweating that I could measure. My fluid loss for swimming was under 0.1 L/hr.

So I now had my expected and approximate sweat rates for swimming, biking and running. Next, I wanted to learn more about sodium and electrolyte loss and replacement. The easiest and most cost effective option was to do a Levelen sweat sodium test. For $75, Levelen will send you a piece of gauze to tape on your forearm during a short run to collect sweat and sodium. They also provide you tweezers and a tube to pull out the gauze after the workout and ship them back the sweat soaked gauze for analysis. I did this simple test during a 45 minute run in 75 degree weather. Here were the results:

Sweat Rate               2.42 L/hr

Sweat Na+                61  mmol/L            3395 mg/hr

Sweat K+                  7.0 mmol/hr

Sweat Cl-                   60  mmol/L            5140 mg/hr

NaCl loss                    8.5 g/hr

levelen results

Just as I expected… I was on the extreme end of the scale for sweat rate and also sodium loss. The above equates to 1403 mg of sodium lost per liter of sweat. That’s a crazy amount of sodium! The FDA RDA for sodium is 2300 mg per day for an adult. That means, in 1 hour of running (3L of sweat), I lose almost 2 full days intake of salt…. In 1 hour!

So now, I had a good idea of my sweat loss rate and also a data point for my sodium loss rate. Now the question is, how much do I need to replace during a race. All of it? Some of it? None of it? Certainly, I knew I needed to replace most of my fluid loss. I know that when I get below 155 lbs of body weight I feel pretty crummy and fall apart on the bike or run. So I know I can’t lose more weight to get below 155 (or I cramp up and can barely move). But what about sodium? I’ve never really taken salt pills or any sodium supplement outside of what was in my sports drink and food.

The new school of thought, specifically from people like Tim Noakes and Phil Maffetone is, you just need to drink to thirst and do not need to supplement with electrolytes like sodium. I have been following Tim Noakes and his ideas for a while. I have read his book Waterlogged, and listed to countless podcasts and read countless articles from him. His concept is very appealing because it relies on listening to the body and only drinking when thirsty. This is really appealing because it takes all the work out of trying to stay hydrated… just drink when you’re thirsty and you’ll be fine. Noakes also doesn’t recommend sodium supplementation when exercising because, he says, our bodies have enough internally stored sodium to sustain us and that sodium loss (as measured per the test above) has more to due to your daily salt intake from diet than your sodium needs during exercise.

The problem for me is I have used this theory and have had very limited success with it. I tended to train and usually race using thirst as a guide for water intake, and also not supplemented with any sodium. The problem for me, as mentioned above, is I always fall apart on hot days or long workouts. All my race rehearsal training days, where I worked out for 5-8 hours, have always been huge failures due to dehydration (as measured via body weight loss). I always cramped up so bad I could barely move and barely made it home. I feel like I’m pretty in touch with my body and how I’m feeling, but maybe I have no idea when I’m thirsty and I don’t drink when I should. Whatever it is, the drinking to thirst theory doesn’t seem to work well for me right now.

I decided for Kona, to not follow that school of thought and go back to a more prescribed approach to fluid intake and sodium intake, at least as a starting point.

So next I needed to figure out how much fluid and sodium I should take at Kona. On the bike, I knew I could manage the 1.5 L/hr of water I would be losing as I had practiced taking in this much water quite a few times. The run as another story. There is no way I could drink anywhere near 3 L/hr to replace all my fluid loss. I’ve heard some say that about 800 mL/hr is about all you can absorb. I was hoping that wasn’t true.

I next contacted Skratch Labs to get some help. They seemed to be really on top of helping endurance athletes with their hydration needs and I liked their products for all of my training. Skratch was a great help, and after a couple back-and-fourths over email, I got a great understanding of how they approached hydration and fluid replacement. From this I began to build out my baseline formulas for my Kona hydration planning.

The starting point is your baseline body weight and then a maximum acceptable dehydration level. Skratch said that they have seen 4% dehydration as an acceptable level before performance loss. I would agree with this based on my data, as my baseline body weight is 162 lbs, so 4% dehydration would be about 155 lbs (right where I notice I begin to fall apart). From there, they key is really pre-loading with fluid before starting the race. Using something like Skratch Hyper Hydration Mix, you can use the extra sodium it has to help with water retention to preload your body with sodium and fluid.

If I am able to pre-load my body with fluid, and taking into account an acceptable level of dehydration throughout the race, I can come up a level of fluid replacement needed in the race which will be a certain level less than the fluid lost due to sweat.

Here is my data I put together in preparation for Kona:

fluid calculations 1

I start by entering my body weight and level of acceptable dehydration after the race. I also enter anticipated race times (don’t need this too much as you can plan on a per-hour basis if needed). I then enter all my expected sweat rates for swim, bike and run.

The output on the right, shows my acceptable fluid deficit per hour in mL (293.9). This means, for a 10 hour race, I do not need to replace 293.9 mL per hour of my sweat loss. So if I sweat at 1 L/hr, I would only need to take in (1L – 293.9mL) 706.1 mL/hr of fluid in order to be fine and still be at only 4% dehydration after the race.

From there, I estimated I can pre-load fluid the days leading up to the race and race morning up to a total of 1.5 L. This would mean my body would be heavier when I started the race by that extra 1.5L of fluid I would be holding (with the help of sodium). This would then put my acceptable fluid deficit even higher at 443.9 mL/hr.

In the totals you can see I expected to lose 18.8L of fluid during the race but only needed to replace 14.4L during the whole race.

Next is to figure out how to replace that 14.4L of fluid throughout the race. I obviously cannot replace it during the swim (unless I end up drinking ocean water).

fluid calculations 2

I played with different replacement rates for swim, bike and run. I put in 0% for swim, since I would not be drinking any during the swim. I tried to hit over 100% replacement on the bike, just because I knew it was easier to handle drinking water on the bike than while running. If I hit 102% replacement of fluid on the bike and only 57% replacement on the run, then I still could hit that 14.4 L of total fluid needed. I thought this would be the best strategy for me in Kona.

This level of fluid replacement ended up being about 70% of my BTA bottle per aid station on the bike and about 10 fl oz of fluid per aid station on the run. Pretty doable.

One other very important thing to note (that Skratch brought to my attention) that plays into this is managing body temperature. If I could use external cooling to lower my sweat rate, I would be in a much better position and not need quite as much fluid replacement, and more wiggle room with these numbers. Keeping the body cool by dumping water on your body during the bike and run, and using ice could really bring down my total fluid needs by reducing my sweat rate. I didn’t know how to really quantify this, but I knew I chose moderate sweat rates based on Monterey temperatures so, I figure I could just use as much cold water and ice as possible as an experiment in Kona. If anything, I would just be less dehydrated at the end of the day if all worked out.

Now that I knew how I planned to replace fluid in the swim, bike and run, I just took my sodium loss rate and figured out about how much sodium I needed to hour and per bottle of water I took in. This would not be all the sodium I lost in sweat, but just like water, I would replace most, but not all, sodium loss for the day. I then thought about when I could take in Skratch Hyper Hydration (pre-swim, bike special needs) and added up how much sodium what was. I took my total sodium needs, subtracted what I would take in from Hyper Hydration (and what is in my food I take in during the race) and then calculated about how many SaltStick pills I would need per hour or per bottle of water.

All of this is a bit overkill, I think. I really just wanted to use this as a starting point to figure out how to manage sodium and fluid intake for Kona. I think sometimes, you can overanalyze things which ends up hurting more than helping. But I guess that’s all part of the fun of triathlon. Triathlon is one big problem (or maybe lots of little ones) that is fun and interesting to figure out.

In the future, I really want to do another sweat-sodium test for another data point to further validate my own data. I think I have a much better idea of my fluid needs, but am only really scratching the surface on sodium needs. Plus what about all the other electrolytes! I think I would really need to spend a lot of time training and racing in the heat to really dial this in, which probably isn’t going to happen any time soon.

Ironman Canada Race Report


This was my first visit to Canada so the trip to Whistler was highly anticipated for me. I will say, that the drive from Vancouver to Whistler is just amazing. Lots of thick green forest mixed with steep rock faces and aqua-blue water. The scenery did not disappoint. We got in to Whistler the afternoon of Thursday before the race and settled in to our hotel before walking though Whistler Village. The village reminded me a lot of other mountain ski towns in the summer such as Tahoe. The venue seemed a bit different from other Ironman events I have been to. Normally, Ironman seems to be the center of all activities, but in Whistler, Ironman seemed like a small event amongst a lot of other visitors and activates around the area. The downhill mountain bike scene seemed to really be front and center in terms of what people where there for. What’s great about the village is all the food choices and even a nice grocery store for anything you could ever want in addition to lots of options for coffee and dessert.IMG_8967

I made my way down to the Ironman village, and picked up my race wheels from RaceDayWheels.IMG_1587 What was nice about this trip is I didn’t bring any wheels with me. I brought only my bike, which saved me an extra checked bag. I used my Ruster Sports Hen House with their new carat case to pack up my Dimond bike (super easy by the way) and just put my rented wheels on when I got to Whistler.

On Friday morning, after coffee with the family,IMG_1618 I decided to take my bike out on the road for a quick ride and make sure everything was in working order. The weather report called for scattered showers throughout the day and I wanted to get out before more rain came in. DSCN0759On my ride, the roads were pretty wet, but at least it wasn’t raining (I hate riding in the rain). I rode 15 minutes on the highway toward Pemberton and then back. The roads, aside from the puddles, were in great condition, and I was looking forward to having the whole lane for the race instead of just the shoulder. I spent the rest of the day, relaxing with the family and enjoying the area by doing the Peak2Peak gondola ride.

IMG_0690Saturday morning was bike check-in day. They had early bike check in at 9:30 for AWA athletes, so I packed up my bike and run bags and rode the 2 miles to Alta Lake and T1. There weren’t many people there yet as the shuttle busses hadn’t started yet. I racked my bike and covered the aero bars and seat with some plastic bags I had. I really didn’t like the idea of leaving my nice Dimond in the rain all night. Right after I checked in my bike, I got my wetsuit on and swam an easy lap in the lake. The water temp was great. IMG_0711Basically, it felt like swimming in a pool, not too hot and not too cold. There was a bit of chop from the wind which made going out a bit harder than coming back. Overall, it seemed like a great swim venue.IMG_0715

The rest of Saturday was just relaxing with the family (and checking the weather every 3 minutes). The weather report for race day showed a lot more rain than both Friday and Saturday. I was a bit worried because I really never ride in the rain, so I wasn’t excited about spending all the time wet on the bike. I figured rain was still better than being hot.

Race Morning

Sunday morning my alarm went off at 4:30am. I actually got a decent nights sleep, falling asleep a little after 9pm and only waking up a couple times at night. My goal was to eat breakfast before 5am to give me a couple hours before the cannon went off. Breakfast was a couple bowls of granola and milk with raspberries and a sliced apple with lots of nut butter on top. After breakfast and getting dressed I made my way down to T2 to get on the bus to T1. I was happy it wasn’t raining yet, but the ground was soaked and the sky didn’t look too promising.IMG_1643

T1 had its typical nervous energy as everyone went about their morning routine. I didn’t have much to do as I decided not to even pump up my tires due to the wet road I knew was ahead. I spent most of that hour talking with friends and trying to enjoy the experience. I finally put on my wetsuit and headed toward the water to watch the pro start. I tried to wait till the last minute to get in the water as I didn’t want to waste any energy treading water before the start, and I’m not one to warmup before an Ironman.



I really like mass starts. They are much more energizing for me. When the cannon went off, I started my swim fairly strong and settled in with the masses of others, trying to find feet to follow. There wasn’t too much contact as I didn’t start right along the buoy line, but a little offset, towards the shore to try to find a cleaner (but longer) line to the first turn buoy.

On the way to the first turn, I could tell it had started to really rain…hard. I felt bad for all the spectators out in the rain watching. Then I started to think how wet I was going to be on the bike. The first and second turn got a bit tight, but I slowed down and took my time around the buoys.

Overall, the swim was pretty uneventful. I really only have a couple speeds when I swim, so I don’t really think about pace, but just try to swim strong without too many hard efforts. Towards the end of the second lap, we started coming up on swimmers finishing their first lap. Things got a little more chaotic as the group I was with tried to get around and find a clean line. After the last turn buoy, it felt like there was a lot more chop in the water, and that last segment really seemed to take forever.

I walked out of the water and over to the wetsuit strippers who helped me get my wetsuit off, then I was off to the changing tents.

Swim Time: 00:59:29


The first thing I noticed in the tent was how hot and muggy it was in there. It was also really busy. I had to find a chair toward the far back because most of the chairs were already taken. I guessed it was due to the bad weather and everyone taking a little longer to put everything on. I struggled for a bit getting my arm warmers on and rolled up… not too easy when you’re wet. I put on my shoes, helmet and gloves and headed toward my bike. I did have a wind breaker in my bag, but chose not to put it on since at that time, I wasn’t cold at all. Probably a big mistake.

T1 Time: 05:33


It was raining pretty hard when I got on my bike and started settling in. Just a few minutes into the ride, and I was already soaked through and starting to get cold. Within a few more minutes I could feel my jaw shattering and my whole body started to shiver and shake. I was getting really really cold, and I couldn’t stop shaking. I wasn’t hungry at all, but I tried to get in some nutrition by drinking some of my UCAN and eating a gel. My goal was 300 calories and hour on the bike from mostly UCAN and a few gels (just to mix it up). It was really hard to even drink from my bottle as my jaw was tight from shivering so much. By the time I got to the base of the Callahan climb, I was in full convulsive shivers.

I was really looking forward to the long climb up Callahan by then, hoping I could up my power and warm up a bit. No such luck. Sitting up out of aero, I got hit with more wind on my body and it made me even colder. I was starting to become really miserable. More miserable, than I have ever been on my bike and definitely the longest I had ever been that cold. All the way up Callahan, I kept thinking about how was I ever going to run off this bike feeling like this. My whole body was shivering and my lower back was even shivering and aching. I was really worried about all the wasted energy my body was using shivering: I needed that energy for the run.

Going down Callahan was really bad. I was ice cold. I tried to take it really slow, but I didn’t have much braking power at the time. My wet brakes on carbon wheels weren’t really doing much to slow me down. On top of that, I could barely squeeze the brakes, my hands were so cold and my bike was shaking like I had speed wobbles from my shivering as I went down. After making it down Callahan, I made my way back to Whistler village and then out toward Pemberton. The whole time, I was just doing what I could to stay warm. I was freezing and shivering all the way to Pemberton.IMG_1709_cropped

Once I made it down to Pemberton and started the long flat section, the rain started to ease a bit and I started warming up. I began to feel a little better and even stopped shivering. It wasn’t till then I was really able to look around and enjoy the beautiful scenery. I still felt pretty strong along the flat and was able to hold power and get back to focusing on my nutrition.

The long climb back to Whistler seemed to go on forever. Most of the climb back wasn’t too steep, but there were sections that had a good grade and really slowed me down. From Pemberton, I had about 20 miles up climbing to make it back to Whistler. The first 10 miles had some good climbs broken up by some short downhills. The second 10 miles was a lot better and was just a slight uphill grade, but I could at least stay aero. This last section really got me tired, and I was seeing my power harder to hold where I wanted it. I was just ready to get off the bike.

I finally made it back to the village and tried to stretch a little while coasting through all the chutes until T2. I was still very stiff and my lower back was more tight and sore. I finally was able to get off my bike and make it into the T2 tent.

Bike Time:5:40:42


I was really slow moving in T2. I left my arm warmers on, just in case the run was cold, but took off my gloves and even changed out my socks for dry socks. I was really moving slow. I had to hit the washroom on the way out in order to get everything out of my bladder, and that added another couple minutes to my already slow pace getting to the run.

T2 Time:3:34


Right away on the run, I could tell it was going to be a tough day. I usually have good energy from the crowd and seeing family coming out of T2DSCN0765, but this time, my energy was low and my body was already achy. I had to really slow down my pace and I was really worried I’d be walking later in the run based on how I was feeling. Right out of T2, there is a nice climb which really hurts. So right away my heart rate felt like it shot up and my pace dropped back to what felt like a crawl. On the gravel and dirt trails, I wasn’t feeling too great. My stomach started to bother me and I had to walk a small hill because I didn’t have the energy to run it. Due to my stomach being upset, I really wanted to stop and rest to see if I could reset myself, but I kept moving past aid stations without stopping.IMG_1741

Around 4 or 5k, I saw a bee land on my chest, and then felt the sharp pain of its stinger. I cursed out loud. I figured this was a sign I needed to stop. I found the next aid station and stepping into a porta-potty and sat down. I looked for the stinger in my chest, but there wasn’t one there, just a small red mark. I ended up sitting there for about 4 minutes. I knew now, my run time was going to be way off my goal, but at least that took some pressure off me to go too hard. I eventually made it back on course and started running again. My average pace had dropped to 8:30 already with the stop, not good compared to my goal and what I knew I could do.

I slowly started to feel a bit better in my stomach. Just stopping somehow reset everything and I began to feel normal again (normal for the marathon part of an Ironman). I was able to get my pace back to 7:50 or so, which is still slow for me, but much better than walking. I ditched my arm warmers as the sun started coming out from the breaking clouds.

I mentally, just thought about completing the first lap. After 13 miles, I gave myself permission to take Pepsi at the aid stations (I was only doing on-course Gatorade till then). Also, mentally, after the first 13.1 miles, it feels like the home stretch. I made it through the first lap and started the second lap. I then told myself just to keep it up till mile 18. Mile 18 seems notorious for when the wheels really start coming off for most people. At mile 18, I was still going, slowly, but still chugging along.

What was nice, was I never really got to that deep dark place at mile 18 or 20 like I knew could happen. I think maybe the slower run helped not burry myself too deep after that brutal bike.

I finally made it to the turn off, where you go left to make another lap, and right to the finish. I was almost there…. Or so I thought. That last section seemed to go on forever. There was a little more uphill, some windy paths, and a long loop up through the village path before making it down to the finish shoot.DSCN0778

I was able to ear my name being called as I crossed the line.

Run Time: 3:35:26

Race Time: 10:24:44, 8th in AG


It was truly an epic day. Hearing the stories from others who went through similar challenges on the bike, made me feel a lot better. Through a lot of the bike and run, I thought I may be walking to the finish, so I’m really happy I was able to keep going.

I’ve never been a bath person, but I have never wanted to get in a hot bath so much in my life as when I finished. After getting my stuff and hobbling back to the hotel, I sat in the hot bath until I finally got some feeling back in my limbs.

I’m really happy I chose Canada as the venue for my first Ironman of this year. It’s a great location for this great race. Even though, the weather wasn’t ideal leading up to and on race day, it’s still a great place for family and athletes. I also learned a lot about myself from this extra-hard experience. It was even sunny and warm the next few days while we finished out our vacation in Whistler and Vancouver.



The Dream

When I first started preparing for Ironman racing I didn’t really understand why so many triathletes spend so much time obsessing over changes to their bike or position or buying new and more aero equipment that saves seconds or maybe minutes over an Iron distance bike race. I understand that obsessing, talking about and planning are all part of the fun and lifestyle of the sport. But I didn’t understand why a couple minutes over a 10 hour race would really matter all too much. After I did Ironman Chattanooga, my opinion changed a little bit. I had placed third in my age group. The fourth place finisher was less than 2 minutes behind me and fifth place was under 2 minutes behind him. I was lucky enough to get a spot to Kona for my finish, but it made me look at those seconds and minutes a little bit differently. If, for Chattanooga, I hadn’t had a disc wheel, or hadn’t used an aero helmet, or had listened to my wife, and not shaved my legs, I most likely would not have received the Kona slot. Now what if I was on a faster bike, maybe I could place even higher. I began to see that little things in aggregate make big differences.

It was this reasoning, or maybe I just like buying new things, which made me start looking at what fancy new things I could upgrade for 2015. The most obvious was the bike itself: the foundation (and most expensive) of triathlon purchases.

Of course, the lure of a high end super bike is everywhere in triathlon. My research led me to a few options to drool over. I could dream of going after something tried and true like a Shiv or P5, or I could be a bit more risky with some of the latest hype over beam bikes. I started reading about beam bikes, and specifically the new Dimond and I really liked the concept and the look of the bike. It seemed like the rebirth of a great design, mixed with some new innovation. The story behind the Dimond also resonated well with me. Made in the USA by a small, emerging company.

As if the folks at Dimond were reading my mind, I got a nice informative message from them around the same time as I was doing my research on the bike. After learning a bit more from them about their bike and their company, I decided to take a big step and order my own Dimond frame, which they would make for me and have ready at the beginning of 2015. I will also say, that working with Chris at Dimond was a great experience. He was super responsive and helpful when it came to the whole process. I can’t say enough about the customer experience during the whole process.

Making it Real

While I waited for my Dimond frame to be built I had time to think about the components I wanted on it. I was really excited to be able to finally make the move to electronic shifting. I know I wanted to stick with Shimano, the real decision was Ultegra Di2 vs Dura Ace Di2. From everything I read, they seemed to function about the same. There was just a 1 pound weight difference between the 2. Deep down, I knew Ultegra would be the best option and save some money. However, I almost felt like such a high-end bike “deserved” the best of the best, which was Dura Ace. I know everyone riding bikes is very weight sensitive, and one pound is a lot of weight on a bike. However, it seems, that recently the consensus for triathletes is aero is more of a consideration than weight in most cases. Most triathlons are pretty flat with little climbing (compared to most road races). In the end I chose the more sensible route and did Ultegra Di2. Here is what else I chose:

Components: Ultegra Di2
Crank: Quarq Elsa RS with Dura Ace 53/39 rings
Wheels: Profile Design 78/Twenty-Four
Tires: Continental Gator Hardsheld
Brakes: Tririg Omega
Stem: Tririg Sigma
Bars: Tririg Alpha with Gamma extensions
Saddle: Fizik Tritone
Pedals: Speedplay Zero
Extras: D-Fly wireless transmitter, Tririg BTA mount, X-Lab cages, Lizard Skins bar tape

Even though I liked the Rotor Power Cranks on my previous bike, I wanted to try something new. Quarq had just come out with their Shimano ring-compatible versions so I thought I would give that a try since Quarq seems to get good reviews. I also chose Tririg for the entire front end of the bike. I liked the look of their bars, and the Sigma stem worked well with the Dimond-recommended Omega brakes.

I was originally going to go for some basic training wheels, but non-aero wheels just look funny on the Dimond bike. So I decided to use a set or aero wheels as training wheels, and I’ll figure out what to race on later. The Gator Hardshell tires are the best training tire (especially around here with all the broken glass on the roads).

Again, the folks at Dimond bikes were awesome to work with and helped me order all my components and even installed everything on the bike for me.IMG_0033 When the bike finally arrived, I was surprised how small the shipping box was. It was amazing to see how small the Dimond bike broke down when the beam is removed. IMG_0034

Due to my personality, I actually wanted to wait to really ride the bike until after I was fully fitted on the bike (I like everything to be ready to go). The Tririg gamma bars come extra long and needed to be cut on both ends. The Dimond seat post also only has an inch or so of adjustment once it’s cut. I didn’t want to do any cutting until I was fitted on the bike.

After doing my fitting with Chris at Burnham Coaching, I felt very happy with how I felt sitting on the bike. I was able to get a little lower in the front than on my previous bike and it felt really good. He did have to cut a little on my seat post and then I got my gamma bars cut down to the right length.

It took some time and figure the best way to dremel out material from the gamma bars because after cutting, there wasn’t enough room to insert the shifters. IMG_0063My father-in-law brought over his dremel and carefully shaved out some carbon to get the shifters to slide in. Once that all was done, I was ready to go out and ride.

The RideIMG_0070

Most people would take a new bike out on a short ride. My first ride was a 3-hour sweet spot (hard) ride. That shows my confidence in the bike and build. I think I may have kept smiling the whole ride. It really feels like you’re batman when you ride the Dimond. It just feels fast. And when you feel fast you go fast. IMG_0077

The Dimond is now my only tri bike and I use it for every ride (except on the trainer or in the rain). I love the way it looks and feels. The bike feels really solid. I like how it handles better than my P3. Even when the roads get rough and I get bumped around in the saddle, I feel a lot more solid than I have before on other bikes. So far so good, on this great investment in speed.
