Weather Conditions

Average High: 60F
Average Low: 35F

The weather can be unpredictable in Arkansas, especially in late February. We’ve had sunny skies, rain, fog, and sometimes all during the same event. Snow is possible, but not anticipated.

Be prepared to face all that the weather can throw at you!

Will I be running in the dark?
Yes. You should bring a light source and back up batteries. At this time of year, the average sunrise is 6:45 AM and the average sunset is 6:00 PM.

What do I need to bring?
At very minimum, all racers will be required to carry a water bottle or hydration pack AND a light (flashlight or headlamp) at dark. Due to the remote nature of parts of the trail, runners will not be allowed on the course without a way to carry water. We strongly suggest you carry a backup light with you at all times. If you’re wondering about additional gear, check out this video from Runner’s World. A cell phone is recommended and and service is good on the majority of the course.

How tough is the course?
Terrain = very hilly, total climb between 100 and 200 feet per mile (5,000 – 8,000 feet in 50 miles)
Surface = trail or dirt road with substantial rocks, roots and/or ruts
