Four Corners Quad Keyah
The Four Corners Quad Keyah is a multi-day running event staged at the Four Corners Monument near Teec Nos Pos, Arizona, on the Navajo Nation from December 3 to December 6, 2026. The series offers marathon and half marathon races held on successive days, with each day beginning and ending in a different state: Arizona, Utah, Colorado, and New Mexico.
Distances:
- 26.2 Miles Marathon
- 13.1 Miles Half marathon
Runners may enter the full four-day series or single-day marathon and half marathon events. The four-day series has a registration cap and limited charity bibs; the single-day marathon and half have a separate participant cap. Events are timed by Rocky Mountain Timing.
Course format and support: each race uses looped courses that provide regular access to personal kit, course food, medical support, and live entertainment. Runners can choose a trail route or a one-mile paved option on race days. Several courses use repeated 5.25 mile loops; half marathon routing includes shorter lap combinations and an out-and-back segment on some days. A baggage drop is available at the Monument Aid Station. Packet pick-up occurs at the park fee booth and runners pay the park entry fee on their first day.
Charity bibs: Navajo Yes and Wander Project offer charity bibs with fundraising minimums for waived registration. Donations are final and charity choices will be verified.
Finishers receive state-specific medals and a range of event swag. The series benefits youth adventure and community wellness programs on the Navajo Nation. Visit the organization's website for the most recent information.
