I sweat quite a bit. I've drank over 3 gallons in a 24-hour period, numerous times. On a typical summer day, I will drink around 2 gallons.
Record for a single ride, eleven 25oz bottles over the course of 67 miles. Over 1oz per minute for 3 and a half hours. I weighed something like 7lbs less than when I left the house, so I sweat out well over 20lbs.
All that said, there's no way in hell I could or would drink 90oz of water in an hour and then figure I was good for the rest of the day. I would have the pee to end all pees about 45 minutes later.
