Figure on a liter/hour if 95+. And don't wait until you're thirsty. Be too late by then. I drank 1/2 liter every half hour, by my watch, and was barely keeping up. Might take a filter if you can't verify taps anywhere on a long, desolate stretch. Might be a stock tank within reach. Or stand on the roadside waving an empty water bottle. Somebody will finally stop.
Actually, it's not likely to be that
hot in Wyoming.
this has certainly been the rough estimate that I have gone by during the last 20 odd years. I used to drink about a bike bottle per hour when really hot (700ml?) and its a pretty common mistake not to drink enough. Having to pee regularly is the key, if you realize that you havent gone in quite a while, you arent drinking enough--and yes, when riding in very hot weather, drink regularly and don't wait until you are thirsty.
A couple of summers ago I rode to Boston and for days it was record temps in high 90s, drank all the time, took advantage of breaks at a/c gas stations to buy cold drinks, and sometimes also found shade in the hottest part of the afternoon and just took a break for an hour/nap.
