One can expect a lot of cramping and pain after thier first race. I was in a world of hurt for a couple days after my first two races- but I am also the type that leaves everything on the course.
You just might have overhydrated. Cut back on your fluid intake and take it nice and easy for the next couple days. Increasing your salt intake may help?

If you drank too much water, maybe it threw your electrolytes out of whack, which will cause cramping and GI problems. Did you take any electrolyte suppliments during the race?

Well, I use only Hammer Nutrition ...so I'd recommend Hammer Endurolytes. You want a combo of different minerals, not just sodium. I'm in Florida, and I need 3-4 tabs per hour in the summer because its so blasted hot and humid. In MI, you would most likely need less, however you need to determine how much water weight you lose during exercise and go from there.

Went to my local bike shop and got some Hammer Electrolytes. Am going to try 1 capsule pre-race. The bottle suggests 1-3. Any suggestions on how far before the race I should take one?

Also, picked up some HEED for the bike portion and will try that. Will let all know how it goes.

I think my recovery was fine (i felt good except for the cramps) and fitness is good--I think it was lack of electrolytes.

Thanks for the help!!!!

Yeah, I would suggest trying something like Gatorade or Powerade instead of water during a lot of the race. Helps to maintain the proper electrolyte balance and is an easy way to get a few extra calories in while you ride to help fuel your run. You may also want to consider adding another gel or two into you nutrition plan while you race. Most Olympic tris are 2-3 hours of excursion, which is a lot on 160 calories.
