Notes
81F 54%H 63DP, at the Alpharetta Big Creek Greenway, supposed to do 8 which I was going to extend to 10, but started feeling a ping in my left calf. Felt it several times, so turned around at around 1.75 miles and headed back. Traffic was bad. Also not happy with the time my 310xt was showing. Thought I was going faster than it was showing.
