The Next Loop 50 Mile Challenge
The 40/50 Mile Challenge takes place at Eddie D Jones Park in Keithville, Louisiana. The event is held on a 5K (3.1-mile) trail-based loop, with participants completing 16 loops to reach the full 50-mile distance. This is a continuous trail race with a mass start, limited to 75 runners.
Available distances include:
- 50 miles
- 40 miles
The event features a 12-hour hard cutoff. Runners have access to a fully stocked aid station at the start and finish of every loop, allowing for simple fueling and logistics. Participants may stage personal gear at their vehicles or in a dedicated staging area separate from other event series participants.
The race uses chip timing to record and post splits for every completed 5K loop. Age group divisions include Open, Masters (ages 50-69), and Grand Masters (ages 70+). Pacers are permitted to join athletes after 4:00 PM. Pacers must check in at a designated station, wear official identification, and are not allowed to carry gear or nutrition for the runner.
