Contestants have the chance to win $1 million every time they run the Million Dollar Mile. Standing in their way is the most challenging course ever designed and a group of elite athletes with one mission: to stop the contestants from winning the money at all costs. Tim Tebow, former college football champion and NFL quarterback, serves as host of the high-stakes physical competition series. Matt "Money" Smith, the L.A. Chargers' play-by-play announcer, and Maria Taylor, ESPN host and reporter, serve as commentators.
