My knee totally burned after day 1 training. It's been a year and a half since I injured my leg. There is a definite divot in my leg that hadn't been there before the injury. Still nothing to be done about it.
Day 2 no burning, but calves sore in the back as they should be. Training included increase in run time.
Day 3 Legs feel pretty good, but it is Saturday and that means a lot of walking and grocery shopping and chores. It's also 103 degrees. No training today.
