Mamba 100, Memphis, TN
The Mamba 100 weekend offers multiple distances on the Wolf River singletrack at the Wolf River Refuge Trailhead in Memphis, TN. The event includes the following distances and loop structures:
- 100 Miler : 7 loops plus a 2-mile start section, approximately 100 miles
- 100K : 4 loops plus a 6-mile start section, approximately 62 miles
- 50K : 2 loops plus a 3-mile start section, approximately 31 miles
- 25K : 1 loop plus a 1.5-mile start section, approximately 15.5 miles
The course is built around a 14-mile loop of mostly flat, smooth single-track with a short lead-in before the loop. Two primary aid stations serve each loop: a Bridge Aid Station (around miles 4.5 and 9.5) and the Start/Finish Aid Station (mile 14). Runners can expect aid approximately every 4–5 miles and a variety of packaged and hot foods during evening hours. Tailwind is listed as the primary race hydration; water, electrolyte drinks, and other standard ultramarathon nutrition are available.
The 100 Mile is a Western States qualifier with a 34-hour cutoff to earn WSER qualification. Packet pickup is scheduled at the Start/Finish trailhead on the day before the race; canopy setup and drop bag policies apply at that location. No refunds or bib transfers are permitted; entry deferral credit is available on a sliding scale depending on notice. Pacers are permitted for the 100 Mile and 100K under specified rules. The race is Trail Sisters Approved and awards buckles or medals to finishers by distance. Visit the organization's website for the most recent information.
