A long run or fast workout is hard enough, let alone a race. Like a friend of mine always says: In the heat, I don't compete! Even if you just take your run easy and skip the hard workouts, how are you even supposed to just feel good when running in the heat and humidity of summer? Training well through the heat and humidity of summer takes a careful approach that combines timing, gear, and an understanding of why exactly it's so damn hard to run in the heat in the first place. But of course, it will still be tough. A few weeks ago at the Heartbreak Hill Festival put on by Runner's World, I was talking to another runner about a race she ran in Miami.
