This week Dave and Joe, Chasing Tomorrow podcast co-show hosts, are talking to Chris Roberts, the "assist" at the Big's Backyard world championship.  Chris completed 84 laps, for a total of 350 miles over three and a half days.  He came in second to Harvey Lewis the winner.  Chris talks about his race and the challenge of overcoming a serious knee problem to break the world record of 81 laps and to take the race to another level.  Let's not let Chris' humble demeanor hide the fact that he is an incredibly tough competitor and a guy to watch in future impossibly hard ultras (maybe Barkley Marathon's).
