On Sunday, I completed the NYC Triathlon and had a similar experience as a couple other races this summer. Towards the end of the race, I experienced what felt like an upset stomach. I also lost about 5 lbs. of weight (determined by weighing in before and after the race). I weigh about 177 lbs. and have about 13% body fat. I basically sweat a lot, especially on hot humid days. I'd like some advice about race hydration and nutrition strategies. During the run, I drink a couple cups of water at each water stop, but if I drink more, if start to feel more bloated and uncomfortable. I would like to discuss strategies.
I have the Queens Half Marathon on Saturday and a half ironman in August. I'm not sure if I should try the Half Ironman on a hot August day.

Hey – congrats, that is incredible that you completed the NYC Tri – be proud. Sounds like you came upon a complicated bind at the end of your race, sorry to hear. First off, there is something called overhydration — hyponatremia. It’s when the body actually has too much fluid and begins to have major electrolyte disturbances. Sodium is low as a result, and it isn’t fun. You sweat a lot, which means you are losing a ton of fluids and sodium, as well. The goal is to drink around 4-6 oz every 20min, preferably a diluted gatorade or propel water. Is that what you are doing now?
