Description

Sky Peaks is back at Arizona Snowbowl!

Runners will have the unique opportunity to climb up to 11,500ft, making Sky Peaks Arizona's highest footrace.

On Friday afternoon, runners will tackle the Agassiz Hill Climb, taking a gnarly route to the top of the Arizona Gondola. After climbing 2,100ft in just 1.4 miles, runners can (thankfully) take the gondola back down.

Saturday brings a full slate of racing, with distances ranging from 5K to 50 Miles. All races (except the 5K) start with the 3.4 mile "Agassiz Loop" a grueling route that circumnavigates the Arizona Snowbowl property and tops out at 11,500ft. After that little "warm up", each distance continues to their respective courses. The 5K stays pretty flat and does a wonderful loop through the Aspens.

NEW for 2026 are the fixed time events! Runners who enjoy this level of pain will stay on the Agassiz Loop for either 6 or 12 hours, racking up 2,000ft per loop!

Sunday will bring the final test of the mountain legs. The Mountain 6K will start at Agassiz Lodge, top out at the Arizona Gondola, and then sprint down the ski runs. The Mountain 20K will be a point to point race where runners will be shuttled to Fort Valley Trailhead to start their adventures. This race will start at 7,200ft and climb to 11,500ft before descending the ski slopes for an epic finish at Agassiz Lodge.  

Fall Foliage

When you think of Arizona, you don’t think of acres and acres of uninterrupted pristine forests. But that is what you get in the Coconino National Forest, one of the most sprawling and diverse National Forests in the country. A walk in these woods any time of year is a sight to behold, but this fall, if you make the trip to Flagstaff Sky Peaks Mountain Runs, you will see the blinding golden foliage of the quaking aspens, which only grow at elevations of 6,000 to 8,000 feet. These towering white-barked slender giants seem to dance in the slightest breeze and rain down their shiny golden leaves.

The Fall race date will give you the chance to run through the aspens at near-peak color!
