5 miles: The coming sauna

I did the 5 mile "free" run today to Starbucks. However, the free run over the summer includes a hand-held water bottle (0.6 liters, 1 endurolyte). It was a sunny 83 degrees with 59% humidity. It felt like I was running in a sauna. Sadly this is nothing compared to what is coming this summer. Oh, the south.
