My resting HR was 47 again. When I left home the temperature was 42 with wind gusts (according to Yahoo! Weather) of 15-25 mph. I'm running out and back, and I had a head wind on the out portion. It was hard to run against 20-25 mph gusts. I was looking forward to a tail wind on the way back, but the wind died down and the gusts were about the same speed I was running. My time was only 30 seconds longer than on Monday, so the small tail wind helped some.
