The Flat Top Mesa Endurance Run takes place Saturday February 14 to Sunday February 15, 2026 in Mesquite, Nevada (1635 World Championship Way, Mesquite, NV 89027). The event offers four trail race distances on a loop course: 100 Miler, 100 KM, 50 Miler, and 50 KM. Registration and event pages list entry fees for each distance.
Course
All main distances use a counter-clockwise loop of approximately 10 miles per lap. The loop starts and finishes at a parking lot near coordinates 36.80445, -114.13872. The route runs on desert trails with packed dirt, rocky sections, and open vistas. Elevation on the loop ranges from about 1903 ft to about 2333 ft, with a net change near 430 ft per loop. Aid stations include a water station near the loop start and a mid-loop Aid Station 2 around mile 5.
- 50 Miler: five 10-mile loops (about 50 miles)
- 100 Miler: ten 10-mile loops (about 100 miles)
- 50K: three 10-mile loops plus a 0.5-mile out-and-back (about 31.1 miles)
- 100K: two 50K courses (six loops plus two 0.5-mile out-and-backs, about 62.2 miles)
The 50K and 100K include a 0.5-mile paved out-and-back on a nearby bike path to reach the exact distances. The course description notes steep climbs early in each loop and a steep final descent on technical terrain. Visit the organization's website for the most recent information.
