Four Corners Quad Keyah
The Four Corners Quad Keyah runs from December 3 to December 6, 2026 at the Four Corners Monument near Teec Nos Pos, Arizona on the Navajo Nation. The event spans multiple days and is staged at the Four Corners Monument.
Events include:
- Four-day marathon series
- Four-day half marathon series
- Single-day marathon and single-day half marathon on Sunday, capped at 100 runners
- 2-mile Community Fun Run on Saturday
A marathon and a half marathon are offered each day, with each day's race beginning and ending in a different state: Arizona, Utah, Colorado and New Mexico. Runners may choose a trail route or a one mile paved option each day. Trail marathon courses are based on repeated loops; many trail full marathons use a 5.25 mile loop completed multiple times, while half marathons use shorter lap combinations and out-and-back segments. Course routes and surfaces vary by day and are subject to change.
Logistics include packet pick-up at the park fee booth on entry, payment of the park entry fee on the first day, daily swag items and a light breakfast on entry, on-course support and a bag drop at the Monument Aid Station. All marathon and half marathon races are timed by Rocky Mountain Timing.
Finishers receive a state-specific finisher medal each day and assorted event gear. Overall award eligibility requires completion of the trail course each day. Registration for the four-day series is capped and charity bibs and fundraising entry options are available. Proceeds benefit youth adventure and community wellness programs on the Navajo Nation.
