 He'll need 1.83 bottles of water with 23 grams of carbs and electrolytes on this 12-kilometer stretch of a climb. And he'll have the bottles to do exactly that. Wow. Yeah. And this is fun, too. Some teams also have slushy machines. That's because it takes heat energy to melt ice. So a slushy cools them about three times more effectively than straight water. No wonder I crave slushies when it's super hot outside. Okay, so has staying cool in cycling always been this technical?
