Notes
70F 88%H 67DP, at the Alpharetta Big Creek Greenway, doing 8w6bu. I again wore both the 310xt and 910xt. The 910xt registered 0.14 fewer miles that resulted in a pace difference of 12 seconds per mile.
Averaged 11:00.3 mpm for the usual miles 2 through 8. Used metronome 165 which shows in Garmin Connect as 168
