Run - Trail (Nipmuck) 44:42 4.48 mi (9:59 / mi) +123m9:12 / mi ahr:143 max:170 (injured)shoes: Speed Cross Varios 2015
6am run at the hollow. Forgot to allow car scraping time, arrived at the boat launch 5 minutes late. No lights in sight, so headed south on Nipmuck as that is the most frequent 6am option. Moving pretty quickly for a headlamp run, never caught anyone though thought I saw headlamps at one point. They must ventured onto non-Blue trails. Down to terminus and back, coming across Powerline northbound something popped in my R hamstring. Initially painful, then just achy - slow jog back with some walking. Hopefully nothing serious, but skipped the planned 7am & 8am runs to be safe.
