40/50 Mile Challenge - Pinnacle Mountain (May 9, 2026)

Course Description:

Pinnacle Mountain State Park (Arkansas)

​

The course at Pinnacle Mountain State Park utilizes sections of the scenic Kingfisher Trail, offering runners a classic Arkansas trail-running experience through forested terrain with gently rolling elevation. Participants will complete a clearly marked 3.1-mile (5K) loop, returning each lap to a central start/finish area and fully stocked aid station.

​

The trail surface is primarily dirt with some natural roots and uneven sections, providing a true trail feel without being overly technical. While elevation changes are moderate, the course remains very runnable and rewards consistent pacing and smart effort management over multiple loops.

 

This loop-based format allows runners to challenge themselves at their own pace—whether completing a single loop or building toward longer distances—while enjoying one of Arkansas’s most popular and well-maintained trail systems.

 

The combination of natural beauty, repeatable loops, and centralized support makes this course ideal for both newer trail runners and experienced endurance athletes.

Support & Logistics

  • Runners may access personal supplies at their staging area each loop

  • Crew access permitted in designated areas

  • Pacers allowed per event rules (location-specific and time-based)

  • Medical and race staff on site throughout the event

​​

This setup allows runners to adapt strategy on the fly—fueling, gear changes, and rest without leaving the course.

Running Alongside The Next Loop, The 40/50 Mile Challenge runs simultaneously with The Next Loop Endurance Series on the same course.

 

While Next Loop participants run on the hour, 40/50 Mile Challenge runners race continuously and are scored separately.

 

Each event has its own competitive field, results, and rules.This creates an energetic race environment while preserving the integrity of both formats.

The 40/50 Mile Challenge

​

The 40/50 Mile Challenge is a continuous loop endurance race designed for runners who want to push beyond traditional race formats while benefiting from a fully supported, centralized course.

​

Held alongside The Next Loop Endurance Series, this event runs on the same 3.1-mile (5K) loop, but unlike the hourly format, competitors in the 40/50 Mile Challenge run continuously with a strict time cutoff.

​

This format offers a true ultra-distance experience—simplified logistics, consistent footing, and constant access to aid and support.

​

  • Distances: 40 Miles or 50 Miles

  • Loop Length: 3.1 miles (5K)

  • Time Limit: 12 hours

  • Start/Finish: Same location each loop

  • Aid Station: Fully stocked at every lap

​

Who Should Run the 40/50 Mile Challenge

​

This event is ideal for:

  • Runners attempting their first ultra distance

  • Athletes stepping up from a marathon or 50K

  • Experienced ultrarunners seeking a fast, efficient course

  • Competitors who value logistics simplicity and strong support

​​

The loop format removes navigation concerns and allows athletes to focus entirely on pacing, fueling, and mental toughness.
