I recently had the opportunity to interview Mark Dowdle, who has won the Wausau Limitless last man standing ultra marathon two years in a row. This year he ran for 39 hours and covered 158 miles. We discussed his race experience, his perspective as the returning champion, and his future plans including his goal of becoming a professional backyard ultra runner. Topics also included training, support crews, group runs, and the motivations behind participating in such events.
