Today I went on a pretty long ride. The longest/furthest ride I've ever been on, with a pretty burly climb.

During the middle of the ride, I started to notice pain on my whole leg, but only on the right side. My leg, and also my right butt cheek. My right side is still pretty sore right now, but my left side feels fine, just like it should after a ride.

Anyone know what's going on? Is it some fit issues? Technique issues?
