This weekend I finished my sprint triathlon the Boulder 5430 Sprint Triathlon that I've been training for in the last 3 months. The distances were: swim: 1/2 mile, bike: 18 miles, run: 3.1miles
Fuel: I use a combination of protein bars, clifbar gels (specifically Mocha w/ caffeine because I can't stand the fruit flavors), the Powerbar jelly/gummy things, and gatorade.
The Swim: I was so nervous going into the swim. The transition closed 45 minutes before my wave started, and my BGs had be fluctuating all morning pre and post warm up. I had all the normal pre-swim jitters that newbies get, combined with the added stress of fears of going hypo out in the middle of the reservoir. Prior to leaving transition I was 100mg/dl, and had ate approximately 45grams of carbs w/ no insulin bolus. I knew it should be enough to raise my BGs in to a good buffer zone, but I left my meter in the transition area and had no way of really knowing. Next time I'm going to bring a back up meter to the start area, test just before and stash it. The swim itself sucked. I could not get my rhythm down, and the buoys seemed soooo far away! I had trained and trained, and knew I was capable, but couldn't shake the fears that I wasn't going to make it. I had to spend a lot of time on my back, and I stopped to hold onto the kayaks for a rest. However, I didn't have to be pulled from the water and made in 22 minutes. My BG was 118 when I got out of the water. I took one mocha gel before leaving T1.
The Bike: The bike portion was amazing. It was rolling hills and super fast course. The last 8 miles were views of the Boulder Flatirons, which are absolutely amazing. I took 1 more gel during the ride and drank 30g of carbs in my gatorade. I also drank about 12 oz of water during the ride.
Back in transition my BGs were 140mg/dl. I had been checking the dexcom periodically during the bike portion and it was always so far behind the meter that it was useless. My energy balance and requirements were fluctuating so rapidly it couldn't keep up. So I left it at transition for the run portion.
The Run: The run was a slog. I am not a runner, but I kept up my slow pace and pushed through it. It was an out and back and once again on the way back into the transition area and finish I got gorgeous views of the Flatirons. I drank about 4 oz of gatorade from the aid station, so who knows how much carbs, and around 2 miles I ate another mocha gel. When I finished I was at 115 mg/dl.
Overall I finished 90/98 in my age group, which means there's room for improvement! :) Really I'm just happy to have finished, and to have a better understanding of my BG management during competition. I don't think I'm ready to move up to Olympic distance yet, but I definitely want to do more triathlons this summer.
