Escape the summer heat and challenge yourself at the Flagstaff Extreme Big Pine Trail Runs on June 20, 2026, nestled in the stunning ponderosa pine forests of Fort Tuthill County Park, Flagstaff, AZ. With distances including a challenging 50K, a demanding 27K, and accessible 13K and 6K options, there's a distance for every trail runner. The course, organized by the reputable Aravaipa Running, navigates well-maintained single track and wider forest paths, offering breathtaking mountain views as it winds above 7,000 feet. While the elevation provides a significant challenge, the trails are generally well-graded, making it an ideal race for both seasoned runners seeking a fast time and beginners looking to push their limits in a spectacular high-country setting.

Runners will experience the beauty of Flagstaff's signature trails, traversing both the Soldiers Trail and Highlands Trail Loop. The 50K course extends beyond the park to Rogers Lake via the Gold Digger and Two Spot Trails, returning to the start/finish area before a final loop. Well-stocked aid stations, positioned every 4.0 to 7.3 miles, provide water, electrolyte drinks, sweet and salty snacks, and fruit, though runners are encouraged to carry extra hydration due to the elevation and typical race day conditions of highs around 82F and lows around 46F, with a minimal 3% chance of precipitation. The start/finish area, conveniently located at the North Parking Lot of Fort Tuthill County Park next to the Flagstaff Extreme Adventure Course, serves as a hub for drop bags and crew access, fostering a supportive race atmosphere.

The Flagstaff Extreme Big Pine Trail Runs offers more than just a race; it's an immersive trail running experience. Consider doubling down by participating in the "Blackout Night Runs" the evening before for a unique challenge and a commemorative "double down" medal. Runners can also take advantage of discounts to explore the Flagstaff Extreme Adventure Course, adding to a full weekend of outdoor adventure. This event, celebrating its 11th annual iteration, provides a unique opportunity to escape, explore, and achieve your trail running goals amidst the refreshing mountain air and towering pines of Northern Arizona.
