I normally just take water out on my training rides. If i'm going out for more than 40 miles, or i'm planning on going pretty hard i pack a bottle of gatorade and a bottle of water.
I've decided to get pretty serious this year and try racing. I've noticed that damn near everyone at races has some kind of endurance sport specific drink like cytomax. So is anyone else out there drinking this stuff? Do you find it makes a big difference over gatorade or any other basic sports drinks? I guess i could see it working on a longer road race or training ride, but i don't see how it could make any difference on a 45 minute crit or an hour long high intensity training ride after work.
