What was your workout today?
My knees have been killing me the last few days so I took yesterday off, I tried to run tonight, but I mile into it, I knew they would never hold up, so I turned around and walked home. This is driving me nuts.
Are you still screwing around with your position on the bicycle? If so its likely the cause of your knee pain. When poorly positioned on the bike, in regard to seat height especially, your knees take a lot of stress. When properly positioned on the bike cycling is good for your knees.
I put the bike seat a few days back to the original position, where I had it for weeks. I thought raising it might make the pedaling easier, instead it just hurt my knees. The pain is focused around my knee cap, above and below it. The pain has diminished since I moved the seat back, but it hasn't gone away. I don't know if I could be just doing too much riding since I'm not really in that good of shape yet and I've upped my mileage to around 200 a week in the last couple weeks.
How high should a seat be positioned ideally? I have short legs so my seat is lower than most because of that, but to be honest I don't really know exactly where to put it and my LBS isn't much help.
