At the end of my last marathon training set last week, I had to abort my long run. As I mentioned in my previous marathon-related post, my left hamstring cramped and I figured after a few more kilometers that not giving up would probably cause more problems.
By chance when I got home Anna handed me the latest Juoksija -magazine, the leading runners publication in Finland. It just happened to have an article about posture, and it mentioned that forward-leaning posture can cause issues with hamstrings, and it could be fixed by running more erect. I decided I should give it a try, and I did.
I have now run two runs, 4 and 8 KM runs, and while the leg is still sore, I can say that it is getting better now, not worse. I’ll keep you updated.
