Big Butts Trail Run

Big Butts Trail Run

The Big Butts Trail Run takes place on Saturday, July 18, 2026, in Jackson, Mississippi. The start is at the Mississippi College cross country Choctaw Trails pavilion at 5992 McRaven Rd.

The event is a trail race with four distance options run on a 7.75-mile loop course. The distances are:

• 100K
• 100K Relay (teams of 2-4 members)
• 50K
• 25K (listed as a Fun Run)

The loop course uses both cross country trails and Butts Park single track trails. The majority of the course is in the shade. It is described as not technical with a few small hills, featuring approximately 170 feet of elevation gain per loop. There is a 14-hour time limit for the 100K, 100K relay, and 50K races. The 25K has a 7-hour time limit. All races have specific cut-off times for starting final loops.

There are two aid stations on the course. One is at the start/finish and one is on the course. They provide water, Tailwind sports drink, and food. Runners are asked to carry their own water bottle or hydration. Runners starting a lap after 5:30 p.m. must carry a headlamp or flashlight. Pacers are not allowed, but 100K runners may have another runner join them for the final two laps for safety.

The race is presented by MUTS (MS Ultra and Trail Society). MUTS members receive a $5 discount on registration. The registration fees are $40 for the 25K, $50 for the 50K and 100K, and $50 per individual 100K relay member. Prices increase by $10 on June 1. Registration closes on Wednesday, July 15. There is no race day registration or registration at packet pickup.

There are no finisher medals. Top three males and females in each individual race and the top relay team receive custom awards. A $100 prize is offered to any 100K runner who can beat the fastest recorded time of 9 hours, 42 minutes, and 43 seconds.
