Running 1:20:03 [2] 11.6 km (6:54 / km)
Early evening jog through the sauna that is Rock Creek Park during a DC summer heatwave. Ran into Pat Zerfas hiking with poles alongside the creek and a few extremely ectomorphic young male runners - maybe the normal set of people who would be running there on a weekday evening but I'm guessing there was some self-selection for the ability to shed heat to the environment very efficiently.
