So today I did my usual ~4 mile commute (I've been riding to work daily for about a month now, other than that am basically a newbie cyclist) and my knees hurt just a bit when I arrived at work. The inside of my knees specifically. I really want to stay healthy and pain free long term, so I'd like to know what I'm doing wrong! :) It wasn't serious pain and didn't last very long, so I'm not in the damage zone, I just want to make sure that I break any bad habits that I may be starting off with. Any input would be appreciated.
BTW, I don't have clipless pedals or clips (yet) and I'm riding a mtb/hybrid - no suspension, slick tires - if any of that matters.
Thanks for your help!
