Well after three months finally I've hit an injury. After graduating I thought that I would mix things up a bit in order to improve my PR, so a three day week consists of Zombies, Run!, Hill Training and then a run along a flat track. Yesterday I did 5k of hill training and at times I felt I was running on the spot but I did it. Anyway as the day wore on my left leg became more and more sore, and this morning it's still not right, so I googled the symptoms and it seems that I probably leaned forward too much as I dragged myself up the hills on my knees (but I wasn't screaming as much as last time which I took as a sign of improvement!) and as a consequence I've got shin splints with sore calf muscles. So do I listen to my body and not run tomorrow (on a flat for 5k) even if I feel better or should I shake it out?
