About this episode
Dr. Mark has had a busy summer. He recently returned from running the oldest and largest ultra marathon, Comrades Marathon in South Africa. This 89 km course started in 1921 and has nearly 20,000 participants annually. Our Dr. finished a respectable 869 out of 19,524. While he was out there, he also attended the Sports Medical Conference with Dr. Tim Noakes. Check out our web site for more links that we talked about www.trailrunnernation.com
