Dive into the rugged beauty of Flagstaff with the unique Flagstaff Loop Trail 45 Miler. This unofficial "fatass" style race welcomes runners for an adventure that’s all about community and camaraderie, without any entry fees to worry about. As part of this event, participants are expected to bring a contribution such as cookies, chips, or Gatorade, which will be assigned ahead of time via email at least one week before the race. Aid stations along the route provide water and some contributions, but runners should plan on carrying most of their supplies for optimal self-reliance. The 45-mile loop trail winds through diverse landscapes around Flagstaff, offering a mix of challenging terrain that tests endurance while showcasing stunning natural scenery. This event isn’t just about covering distance; it’s an opportunity to connect with fellow runners and the great outdoors in a meaningful way. Runners will encounter varied elevations and trails that weave through forests and open spaces, making this race a true test of both physical stamina and mental fortitude. The lack of entry fees means fewer resources on-site, but the spirit of contribution fosters a unique sense of community among participants. Join us for an unforgettable experience where every step taken is shared with fellow runners and supported by their collective efforts.

About Flagstaff
Learn more about the host city, Flagstaff.
Flagstaff is a city of over 75,000 people (2019) near the San Francisco Peaks mountain range of northern Arizona and the Grand Canyon. At an altitude of 6,990 ft (2,130 m), Flagstaff and much of the surrounding region are substantially cooler than the low desert that dominates the southern part of the state. Though still dry by east coast standards, enough rain and snow falls in the area to allow a forest of ponderosa pine trees to cover the landscape. Winters tend to be cold, and heavy snowfall is expected on an annual basis.
