Big Butts Trail Run

Clinton, United States • 18 Jul 2026

Big Butts : July 18, 2026, Jackson, MS

Big Butts is a trail event organized by MUTS (Mississippi Ultra and Trail Society) featuring multiple distances on the Mississippi College Choctaw Trails and Butts Park single track. The course is based on 7.75 mile loops that mix cross country and single track trails, with approximately 170 feet of elevation gain per loop. The trail is mostly shaded, not technical, and includes a few small hills; late July heat and humidity are noted as an important factor for participants.

Distances:

  • 100K
  • 100K Relay (teams of 2–4 members)
  • 50K
  • 25K Fun Run

There are two aid stations: a start/finish station and one on course supplying water, Tailwind sports drink, and food. Time limits apply: the 50K, 100K, and 100K relay use a 14 hour limit; the 25K Fun Run has a 7 hour limit. Runners may change between 100K and 50K during the event but are not eligible for awards if they drop; 100K and 50K participants may not drop to or be credited with the 25K Fun Run.

Registration details include tiered fees, a member discount for MUTS members, a T-shirt cutoff date, a registration close date, and no day-of or packet-pickup registration. Packet pickup is available at Buffalo Peak Outfitters and at the start on race morning. Safety guidance asks runners to carry personal hydration; late-day laps require check-in with race staff and a headlamp or flashlight; participants 13 and younger must be accompanied by an adult.
