so in other words, just drink a ton of water all the time

if you drink alot of water and doing a marathon I will bet that you will have side pain. that's why in a marathon they have water station in every 3 to 5 mile during a run. 1 cup should be good . to reduce muscle fatigue you will need to it alot of carbo and lot's of training
