Grade: 1
I had taken a running break during the week because of the niggle I felt left top calf behind knee after last Sunday trail race. So I was not going at full speed on park run, just pushing at 2/2 rhythm, when I felt left leg middle calf and hamstring twinge. There seems to be a slight strain there now.
Had a bit of a break from regular training on September UK trip and did not really notice it there.
