Are you an endurance athlete or on the path to running that first marathon or participating as a tri-athlete? Or are you a person who runs that daily 5k?

At first glance you are to be commended because you are clearly doing all you can to stay in condition and keep your heart healthy. But there is a down side.

You know the phrase everything in moderation.  Well, as an endurance athlete you are going beyond moderation and there are some concerns.  For instance, you are more prone to overuse injuries. Things like tendonitis patellofemoral pain syndrome, plantar fasciitis and stress fractures.  You get the idea, a lot of wear and tear. Many of these injuries can be treated by rest or if necessary rehab.

Here is my suggestion.  You need to work with your physician to understand the risks of overtraining. Yes, there are benefits but you need to prevent potential problems.
