Mamba Trail Runners is a Memphis, Tennessee-based trail-running organization founded in 2023 by local ultrarunner James Boler. Its mission is to create challenging, well-supported race experiences that help runners pursue their goals and connect through a shared love of the outdoors. The organization hosts events at area trails and parks, including Wolf River Trails and Shelby Farms Park, with distances ranging from shorter races to 100-mile ultramarathons.

Its featured events include the Mamba 100, Viper 100, Moccasin Ultra Fest, The Great Mamba Hike, and seasonal trail series.
