fixedgeargirl " 4.5 to 11 pounds!?! That's .5-1.5 GALLONS of water! These people obviously had a lot of time to drink!"

can we talk? they don't pee, i've never seen rest stops with porta potties on marathons .... anyone? runners, a little help here? I don't run so really don't know.

On long distance rides we have rest stops and my motto is "you can't stay hydrated if there's nowhere for it to go" so I never miss a chance. If it's hot I'll stop on the way into the stop and on the way out.

One day on the AIDS ride last year I was thirsty but 15 miles to the next rest stop. Then I saw "look, doughnut shop!", so i stopped, asked to use their restroom, bought doughnuts, had one doughnut, passed out the rest one by one to passing riders till done, then hopped back on the bike.
