I haven't been able to run for a week now due to pain in my knees. I have no idea what caused this and the doctor told me to just rest. I haven't walked anywhere for more than 10 mins at a time and they are still very painful! I'm really disappointed to be missing out on a whole week - and possibly more - of running.
When I can eventually start again, do you think I'll need to go back a week? I don't know how quickly you lose fitness :/
