The Zane Grey Highline Trail Runs, a true gem in the Arizona trail running scene, invites ultrarunners to conquer its challenging courses on April 18, 2026, in Payson, AZ. Offering both a 50-mile and a 50-kilometer distance, this historic event is renowned as one of the country's toughest and most unforgettable ultramarathons. Runners will traverse the legendary Highline Trail, established in the 1870s and designated a National Recreation Trail in 1979, experiencing a "Wild West" adventure through the Tonto National Forest. Starting and finishing at the scenic Mountain Meadows Ranch in Christopher Creek, the race promises a community-centered atmosphere with breathtaking views.

The course is predominantly singletrack, with the 50-mile race boasting approximately 86% singletrack and the 50K over 90%. Prepare for rugged, rocky, and rutted terrain, demanding constant attention as you navigate through challenging ascents and descents. The 50-mile distance features an elevation gain of 7,157 feet, while the 50K climbs 4,782 feet, with both routes offering spectacular sweeping vistas across the Mogollon Rim, the southern edge of the Colorado Plateau, and numerous creek crossings. This classic course avoids the burn area known as Hell's Gate, preserving the natural beauty of the ponderosa pine forests and rim canyons.

Aid stations, often strategically placed but sometimes far apart, are known for their support and are staffed by veteran ultrarunners, offering essentials like energy drinks, sandwiches, gels, bananas, and more. Pacers are permitted for 50-mile runners from the 260 Trailhead or Rim Top Trailhead. Typical race day conditions in April present agreeable temperatures, with historical highs around 73°F and lows around 38°F, and a minimal 2% chance of precipitation, providing a beautiful backdrop for this formidable test of endurance.
