So either my knee has changed since the last time I rode more than 5 miles on my road bike, or my shoes have been messed up - but after 20 miles, the outside of my right knee was in so much pain, i could barely pedal (and I was still 20 miles away from home!). My left knee felt great the whole time - but my right foot does toe out a lot (ducklike??) but I think my clipless pedals force them to point forward. It sucked that I didn't feel it until I was 20 miles into the ride - I managed to get another 10 miles closer to home, then started to walk my bike. When walking was too slow and became too painful, I finally put aside my pride and called my husband for a ride (which still meant walking/limping/attempting to painfully pedal) back another 2 miles to a spot that I could be picked up since I was on a rail trail.

I've had this bike 4 years and have had long rides before and never had this kind of pain - do people have to occassionally mess with their pedals?
