About this race
The Viper 300 is a multi-day ultra running event in Memphis, Tennessee, with races scheduled from Monday to Saturday. It provides several distance options: 25K, 53K, 100 miles, 200 miles, 300 miles, ultra categories, and relay entries. Runners can select anything from a long trail-style effort to a significant endurance project.
The main challenge is a 200-mile race designed for those who wish to test their limits of continuous movement. The event's description is direct about its difficulty: this is not a casual weekend run, and the objective is to push well beyond typical race comfort.
