this is a good read for me as i been riding 40 miles a day for the past few months. The heat the other day did make me feel extremely weak, im not sure if i ever got to the point of falling off. But usually i try to push myself, and last week i felt like i should just go slow, and im glad i did.
20 is awfully young to die like this. I think the drinking plenty of water is good advice, and advice i will take.
