I recently did the bike leg of a triathlon. This was only the second time I had done something like this so I wanted to make sure I was well hydrated. I drank water all day long the day before, and a bunch the morning of, and then on the way to the triathlon and while I was waiting for my turn I tried not to drink very much (to prevent strain on my bladder while riding!). This plan didn't seem to work, because in the hour between the time we arrived and the time I actually started, I had to use the portapotty about 10 times! I think I got rid of more water than I actually drank! It was kind of chilly when we got there so I wonder if that was the cause, do I just need to stay warm before a race? Is there anything else that would help? I know that on a hot day I can drink water all day and not go at all, but when I'm at work if I have my water bottle I have to use the bathroom about every 17 minutes! So I am guessing that all I need to do is stay warm but I want to make sure it's not something else, thanks for any advice.

Hydration is very individual: how did you feel during the bike leg? That will be the best info for figuring out how the hydration was for your body.

And sometimes nerves make me have to hit the portapotty, too.

I was getting pretty thirsty just over half way, which wasn't a big problem, I just hate having to take a drink every couple of minutes, while trying not to drop the bottle and still keep up my pace.

How long was the bike leg?
The nice thing about a relay is that if the bike is short enough you can just get a bit dehydrated during it, and you won't be paying for it on the run. But it's one of those balances with not getting so much so that you also pay for it on the bike :)

it depends mostly on your body. The best way to do this is in training for your next event listen to what your body is telling you. Drink 2-3 bottles of water before your training ride and note when you start to feel dehydrated. This mostly pertains to longer rides and "hitting the wall" for centuries I plan to hit a wall at around mile 32 so I usually eat a couple cliffblocks and again at around 75. The problem is by the time you feel dehydrated or feel that you're hitting a wall its already too late.

I found this article because I was curious about the absorption rate of fluids when your not working out. I drink a couple of cups of coffee first thing in the mornings and then hit water for the rest of the day. At work, we have one of those big water coolers, so I keep my 20oz water bottle filled. I tend to drink between 5-7 bottles a day and while I know I'm well hydrated, I think I may be consuming to much water too fast (sometimes I feel a little high from it) and after reading this article I may know why.

Joe Friel (author of the Triathlete's Training Bible) is a top authority for many on training and racing, so you may appreciate his views on what to do before a race.

"Depart for the race site early enough to allow for a traffic jam as all of the racers funnel into the parking area. Also allow ample time for standing in line for body making, finding your rack, pumping up the tires, checking out the transitions, talking with old acquaintances, visiting the toilet several times and warming up.
When you arrive at the transition, rack your bike and position equipment as you always do. Visit the toilet. Acquaint yourself with landmarks for your rack such as its position relative to trees, light poles etc. Visit the toilet. Walk to the swim and bike finishes and location your transition stall from each. Visit the toilet. Rehearse the best route from each to your rack 2-3 times. And of course, visit the toilet."

He goes on to attribute the overactive bladder feeling to start line stress associated with the body's natural fight or flight mechanism. Combine that with more than normal hydration the previous day and all morning and you are expected to be in and out of the bathroom quite a bit.

The fact that you don't use the bathroom much when its hot, but use it much more when its cold should be expected. When its cold you could be taking in more water than needed since you aren't losing any in the form of sweat. When its hot and you are sweating quite a bit but not going to the bathroom then you are still dehydrated. You should of course be drinking more water on hot days than on cold days.

Also something to note is that your bladder shrinks a bit when it's cold. Therefore it can't hold as much so you need to go even more!
