Four marathons or half marathons in four days in four states.
The Four Corners Quad Keys is a unique, 4-day running odyssey at the Four Corners Monument near Teen Nos Pos, Arizona. Runners complete a Marathon and Half Marathon in each of four states over four days. There are paved road and trail options for runners on each day. The road is a one-mile circuit on the main park road, while the trails are challenging routes throughout the park.

All registered runners receive a variety of swag (performance long-sleeve t-shirt, poster, finisher’s medal each day, a unique 4C Christmas ornament and more), plus course support and hearty aid stations throughout the day. There is also post-race food on each day.
There is live music on the course plus a DJ at the start/finish to help keep you motivated on your journey!
