I rode to the gym, taught aerobics, rode back - ~30 miles RT.

On the way back, I got onto the highway for the last mile, because I just couldn't face that second-to-last hill (plus it saved about a mile and a half off the route).

Other than that, it was fine. Ice and Nuun in my Camelbak, and plenty of time to take it easy.

I guess I'm more or less acclimated to the heat for cycling now - in spite of last week's highs in the low 70's - but still doubt if I am for running. On the bike, we generate our own wind...
