The temperture was in the mid 70's and the humidity was close to 95%. In both runs during the last mile when I was really heated up I walked a few steps. The second run I got some water. I really might not be able to make the determination, but I feel that I know when I'm overheating. I get a sense that I've stopped sweating. I actually want to start incorporating some short walking stints during my running because when I run the race I'll have to walk/stop for water, curves, people or other obstacles.
