Gila 100
The Gila 100 is a grassroots trail ultramarathon held in the Gila National Forest of southwest New Mexico. This event serves as the only 100-mile trail race within the forest, which is recognized as the world's first designated wilderness area. The course begins near the historic Fort Bayard, a few miles east of Silver City, and moves into remote backcountry terrain.
The event offers two distinct distances for participants:
- 100 Mile
- 50 Mile
The landscape features a variety of environments, transitioning from high desert hills into ponderosa pine forests. Runners encounter sections of the Continental Divide Trail (CDT), with the course reaching elevations near 9,000 feet. The terrain is described as rugged yet runnable, including long scenic stretches and ridgeline running.
Logistics and conditions for the event include:
- Big temperature swings between warm days and cooler nights.
- Well-stocked aid stations providing hydration, nutrition, and food at key locations.
- A finish line located in Silver City, New Mexico.
The race is organized by Gila Endurance Runs and focuses on a backcountry experience with strong local volunteer support. Registration for the event closes on October 15, 2026. Visit the organization's website for the most recent information.
