The recent heat spell seems to have left New England for now. It will be back, New England is know for changes in it's weather. Which also provides opportunities for frequent reminders on how to beat the heat!
One tip that works for my running is to run in the shade. Amazing to feel how cool it is as you move from direct sunlight into the shade! Too bad that I have yet to find a road completely shaded with stretches along each side of the road so you can switch from time to time.
Looking for such a shaded road also gives you a good excuse to go running!
