I made it to the end of W2 with a lovely first run back at university. I had been worried about running here because there are lots more people around, but it was a beautiful day and I actually really enjoyed it. Unfortunately, my legs are now in a lot of pain. It's mostly concentrated around the back of my knees which seems an odd place! They are most painful when I am going down steps. I was wondering if it was something to do with my new running shoes? They fit well and felt lovely to run in but maybe the change caused some sort of problem? If anyone has any ideas or advice please let me know!
