Summer Heat?

Getting my run on in this summer heat has been rough. I would like to train for a fall 1/2 marathon, either Myrtle Beach or the OBX. Well, the heat puts a wrench in it. I have resorted to running in the woods on trails and late at night, along with just short runs of just a few miles. Hopefully, I will get a few cool days where I can push through 10 miles a few times. I have done so once a month ago when I was testing myself to see if a 1/2 is doable for me.

What do you all do to maintain your running when heat is on?
