Oh, yes, definitely. Through habit and positive reinforcement, the psychological drive to run, train and race grows wildly in some people - and it can grow dangerously large. As a result, people run their way to injury and other serious long-term health repercussions. See the article someone posted above, for notable examples. The mind is so powerful - it can override everything, to the complete detriment of the body. And even if most of the injuries and health problems aren't life threatening - it's truly sad because by overdoing it, you can still kill your ability to run, the thing you love to do. I think to be successful in the long-term - meaning, staying mostly injury-free, improving performance over time, and performing at your peak in your races - is to be absolutely exceptional at governing that psychological drive.
