I mounted my first set of clipless pedals this weekend and went for a fairly fast ride, really seeing the difference that these make compared to toe-clips. But this morning there was a bit of soreness in my knees, and I think I felt it a bit while riding.

I might mention that I am still more of a runner than a cyclist, running 20+ miles a week, especially recently while prepping for a 10-miler and a couple of half-marathons that I'll be doing over the next few months. It was while running that I noticed the knee soreness, but I usually don't have knee problems while running.

Is it possible that I simply overdid it for my first time pedaling with the clipless pedals, or is there some adjustment that I should make to the bike? The latches were pretty tight at first until I got them adjusted and I'm even wondering if twisting my foot outward to release them was straining my knee.

Any ideas?
