About the Flagstaff Sky Race

On Friday, challenge yourself to Arizona’s highest foot race at the Flagstaff Vertical Kilometer. You will climb a total of 1000 meters over a 3 mile course, finishing at the top of Arizona Snowbowl! Don’t worry, you’ll be able to ride the scenic chairlift down after your race!

Races feature a mix of mostly single track trails and some cross country scrambling with significant amounts of climbing! The 55K and 39K start near Flagstaff and traverse point to point courses across Mount Elden and the Dry Lake Hills, the base of the San Francisco Peaks before a final brutal 4,000 foot climb up to the top of the 11,500 foot Agassiz Ski Lift of the Arizona Snowbowl. Then take one final descent to the finish at the Agassiz lodge for post race food and party. Both races are in the US Skyrunner Series in 2017 and serve as the Series finale.

The 2017 Flagstaff 39K SkyRace will be part of the North American Continental SkyRunning Champs where you can earn points towards the World SkyRunning Circuit.
