18 Hours of Fruita

The 18 Hours of Fruita, set for May 2, 2026, in Loma, CO, offers an unparalleled endurance challenge amidst the stunning desert landscape of Highline Lake State Park. While the fast and fun singletrack course, approximately 7.3 miles per lap, is renowned within the mountain biking community, the trails themselves offer an excellent test for runners seeking a unique multi-lap experience. The non-technical, rolling terrain encircles Highline Lake, treating participants to an "oasis in the desert" with lush green spaces, diverse wildlife, and scenic vistas. Expect manageable elevation gains, with individual laps typically featuring around 400-500 feet of climbing.

This challenging 18-hour event kicks off at midnight, immersing participants in the unique experience of night laps under the Colorado sky before the energy crescendos with the sunrise and throughout the afternoon. The atmosphere is celebrated for its blend of competitive spirit and vibrant communal camaraderie, particularly as the race progresses and finishers approach the timing tent area at Highline Lake State Park. Typical race day conditions in early May feature comfortable highs around 70°F and cooler lows around 42°F, with a minimal 4% chance of precipitation.

Runners tackling this endurance feat should be prepared for a self-supported or team-supported experience, as event-provided aid is primarily centered at the main transition area where water and food can be received. The 18 Hours of Fruita is recognized as one of the most beloved endurance events on Colorado's Western Slope, drawing a dedicated community to test their limits on a beautiful and engaging course.
