Many people have told me (non-athletes all) that by doing triathlons or marathons you will, without question, ruin all your joints. I've been hearing this kind of talk, and commented on it on past posts, for going on 7 years now. I would say I'm a student of my sport and I have looked for evidence that this was true. What I usually have found is that the exact opposite is true: If you DON'T engage in rigorous exercise-a minimum of five hours a week, you are going to wreck your joints and back, never mind the wreckage you're visiting upon your cardiovascular system and your risk for diabetes.
If you've had serious trauma to your knees or other joints, then yes, running 26 miles is probably a bad idea (although, maybe not, actually). Well, you read it for yourself:

And...case closed. Let us never speak of this again.
