Went riding at 1pm, had lab work today. The weather was cold, but by the time I got out, it had warmed up about 5 degrees or so. I wore full gear except, no jacket, full gloves, or shoe covers. I felt comfortable most of the way. So, I did modest tempo today, pretty much the whole ride. I did 3 good digs at Banducci wall, SS, and Cummings Valley road last kicker. Ailments, left calve was a little over banducci and on the way back. It only lasted a minute or two. Concentration was ok, but shady on a few places. I didn't feel 100% today. Balance was good, a little off on the last kicke, but other than that, no problems. GPS, HR didn't work till somewhere near Banducci. Gopro, recorded to battery depletion (1:52 hrs).

Forgot to mention, the GPS lasted the whole ride, no low battery warnings...
