Y'know, my tennis elbow gets a little aggravated when riding sometimes on really bumpy/rough roads. Probably from gripping the bars harder to maintain control. Channels more of the bumps through the body, I suspect. It's kind of always with me, but never so bad I can't function. I think I've had it for, oh, about 10 years now (started back in my whitewater kayaking days).

It's also aggravated by extended Chuckit sessions with the dog. So that means less Chuckit and more trips to the creek, which she appreciates.
