Not convinced by this CL. It's not very scientific. What's the incidence in non-runners, lesser runners etc. You're normally a bit more specific than personal, anecdotal 'evidence' which fits with what you believe.

Having said that I think you are right about quality training over quantity.[/QUOTE]

I don't understand your point. Both these runners have had scans or whatever showing worn cartlidge in knees and hips. I also know a very good fell runner who's had to finish because of arthritis in his hip, also in his 40s. These are scientific facts and I wouldn't say its illogical to lay the cause at running's door.
