Great reader question for this post. In fact, two great questions, so I am splitting it into two posts.
“Doesn’t running tear up your knees?” This is one of the more common questions I get whenever I tell people that I am a runner, and I am guessing that most readers here have heard this one a few times as well. For a long time, this has been one of the few (assumed) bad repercussions of being a long term runner. In fact, many runners later in life will often state something to the effect of “all those years of running caught up to my joints”. In spite of all of this, is there evidence that running is bad for your joints???
In short, no. There is almost no evidence to support that statement. In fact, there is more evidence to indicate running could be a protective, positive factor for joints than a negative one!
