Jonathan I live in Colorado Springs and I drink a gallon a day every day so I drink almost 2L of water over a 6 hour period on a daily bases. I know that drinking too much is deadly and not enough can cause major problems in the Ascent and Marathon and also physical problems in the long run. After drinking as much as you did and still felt thirsty you might start increasing your water intake about three days before the race.
I have run the Ascent 8 times and have stopped to P one time.
In response to:
During the 2010 PPM I went through 2L of water up, 2L of water down, stopped at every aid station, drank water and Gatorade, ate salty food and did about 6 gels. I was still thirsty, and NEVER went to the bathroom the entire race. I'm ok with the fact I'm going to have to use an h2o pak during the race but is there something wrong with the amount of h2o I consumed? Or is this normal?
