Known already in just its relatively young history for its reputation as one of the most challenging, difficult marathon events in the Southwest, the Flagstaff Marathon, Half Marathon & 10K is an off-road/trail marathon event that takes runners into rugged, mountainous terrain.
The race — which is set for its 17th annual running this year — is run just to the north of the city, on trails rising into the San Francisco Peaks and the Kachina Peaks Wilderness areas.
