Big Butts Trail Run

Event overview

Big Butts on Saturday, July 18, 2026 is a trail event hosted by the Mississippi Ultra and Trail Society at the Mississippi College Choctaw Trails pavilion in Jackson, MS. The event offers multiple distance options run on mostly single-track trails that use 7.75 mile loops on cross country and Butts Park trails. The course is described as not technical, with a few small hills and roughly 170 feet of elevation gain per loop. Much of the route is shaded.

Distances and format

• 100K
• 100K Relay
• 50K
• 25K Fun Run

Individual 100K, 50K, and a 100K relay are available. Relay teams may consist of 2-4 members with only one team member officially on course at a time. Runners may drop from a longer distance to a shorter one during the event but will not be eligible for awards if they change distance mid-race. 100K and 50K entrants are not allowed to drop to the 25K for credit.

Support, rules and logistics

Two aid stations are provided: a start/finish station and one on course, stocked with water, Tailwind sports drink, and food. Runners are required to carry personal hydration. There are no finisher medals; top three males and females in each individual race and the top relay team receive custom awards. Entry fees and deadlines, packet pickup location at Buffalo Peak Outfitters, and other registration rules are set by the organizer. Visit the organization's website for the most recent information.
