Grade: 2
Abrupt soreness developed after just a couple of controls on first Bennett Pond "sprint". slowing down to a walk didn't much help, and by the time I finished #2 I was in some pretty severe discomfort. I've strained a hamstring before sprinting, but this is the first time doing it at a modest jogging pace.
Still tight, but not sore. Haven't really tried running hard on it, but will continue to stretch it before I do.
