Training in hot weather is not always pleasant, but it’s not always avoidable, either. If you live in an area where the summers are toasty and you want to be in peak shape for a fall race, then you have to get out there and sweat in June, July and August.
While training in the heat is not as enjoyable as running on cool days, it need not be any riskier. Heat illness is relatively rare among endurance athletes, and if you take the following precautions, it will never happen to you.
