In the city we are enjoying very comfortable late-August morning temps. Today, I ran my eight mile tempo run (with a mile warm-up and cool-down) and, as you can see from the picture below, it was a picture-perfect day. At the start of my run the outdoor house thermometer said 72 degrees. The temps are just warm enough to get a little "heat training", but not so hot that I feel miserable for the second half of the run.
1 mile warm-up @ 8:04/mile
8 mile tempo @ 7:14/mile
1 mile cool down @ 7:45/mile
Coming Up: The second of three long runs on Sunday.
