Did my very first mountain bike ride on Sunday on my ebay bargain mountain bike and it was great!

I went out with some of the blokes from my club who took me up hill and down dale and by the time I got home I was completely and utterly worn out!

One thing I did notice once I'd had a bath and some food was that I didn't have any knee pain. Normally when I do a road ride I can start to get a niggling pain in my left knee, sometimes as little as an hour into a ride.

But I just did a full 3 hours as an off - road virgin with loads of climbing and constant effort and not the slightest hint of knee trouble. Anyone got any ideas.

PS I'm sure not complaining...!
