This is a short video about an amazing runner with an inspiring story. David Goggins is an ultra runner from the Navy Seals who doesn't just run, but runs distances far greater than a marathon . Frequently 50-100 miles. The video is shot out in the desert which makes it more impressive. This type of running is not for me but his determination and accomplishments are fascinating.
There is a little bit of his drive in many runners because running requires self motivation and the need to constantly push farther and faster. There is no team....there is no score to compete against. Runners compete against their own limitations.
