I totally overdid it on Wednesday at Body Pump (even though I took my weights down for the squats) and after hobbling around yesterday it was a near miracle of stretching and foam rollering that I was able to go out for my session at all this morning.
Matters were complicated somewhat by a very light dusting of snow that left the paths alternately icy, slushy and dry. Not exactly the change in surfaces you are looking for when supposed to be haring up and down hills. As a result I stuck to the grass alongside the path mostly and wasn’t going to be breaking any records (or any ankles). I figured a session at 80-85% was better than no session at all.
