What are electrolytes? Oh yeah. I've been calling them Athlytes now for about a year. Combine Athlytes with Carnage and you've got the ultimate defense against cramps. I ride in 110 degree weather in the summer for a min of an hour at a time. This stuff rocks. I was handing this stuff out like candy on Halloween to fellow group riders last summer. I think I'm going to add Citruvol Ultra to the stack this summer. I've also read that mint helps with exercise in the heat. I may also add Myco Green powder.
