In this video we join endurance athletes Jeff Browning and Jessie Haynes as they set off to complete the 170 mile trail through the Owyhee Canyonlands of Oregon in just four days time. That’s 42.5 miles per day through some very remote and rugged wilderness for those keeping track at home. The short documentary takes us into the canyons with the two men, as they push themselves to the limit in this stunning landscape that look like quite an outdoor playground. The video is fantastic end-to-end, but it is worth it just to listen to Jeff and Jessie try to figure out their current pace at the very beginning of the film. It turns out, math is very hard when you’re exhausted.
