Thanks v. much,Ow! Sounds as if you're doing pretty well in the circumstances.This kind of feedback is invaluable,partly because clinical findings don't always match capabilities- some dogs have awful hip x-rays, but still get round well, others seem to have a mild problem at x-ray, but suffer more severe lameness;also, we fellrunners have somewhat different activity levels and expectations from our joints than the average population-it's great to hear you haven't been forced to give up by your joints.Cheered me up- I was trying to face harsh reality head-on,but really I'm out to get some real perspective on things.Happy running!
