The Mountain Runners is the story of America’s first mountain endurance/adventure race which took place in 1911 and only ran for three years. The race pit a stripped-down special steam train against modified "Model T" race cars and men against a 10,781 foot volcanic glacial peak, Mount Baker, in Washington State. The grueling 28 to 32 mile marathon race to the summit was frought with intrepid dangers including crevasses, blizzard conditions, and white-outs. Told in a docudrama style, The Mountain Runners incorporates hundreds of vintage images, historic film, graphics, digital effects, and recreated dramatizations starring William B. Davis (the X- Files, Smoking man) with narration by Kevin Tighe (LOST, What’s Eating Gilbert Grape, Emergency!, Matewan.) The film is supported by a cast of Cascadian historians, descendants of race participants, and several world-renowned experts in their field. Interviews with multiple contemporary champion athletes and authors, including: record-holding alpine speed-climber Chad Kellogg and climbing author, Steve House, winner of the Boardman Tasker Prize, and champion ultrarunner Krissy Moehl, US speed distance record-holder, Scott Jurek, ultramarathon pioneer Doug McKeever; and author Cami Ostman (Second Wind, Seven Marathons on Seven Continents,) look back at the accomplishments of their endurance-athlete predecessors with astonishment and offer insights on how the competitors of a century ago may have managed to complete the race.
