Yesterday, I did my 1st run of 2018. After being (again) on IC. No pain in my back, only small 'feeling' in my knee. Today, a little muscle ache in my thights just above knees.
So far, so good. 3.4km in 25 min (excluding part of the warm-up and cool-down -> I couldn't decide when to stop/start to have transitions nice and smooth).
