Here’s what it’s like to run in the Grand Canyon. Well, here’s what it looks like running a small segment of the Grand Canyon from the point of view of some speedy ultrarunners. While supporting a friend on a thru-run of the Arizona Trail on Oct. 4, Jamil Coury just  happened to be near the North Rim of Grand Canyon when Jim Walmsley was on his record-setting Rim to Rim to Rim run. Coury, an ultrarunner and trail race director based in Phoenix, was able to catch Walmsley at the North Rim and run behind him for 2.5 miles down the North Kaibab Trail while shooting this inspiring video.
