Race Overview

The NUTT Endurance Challenge 50k is a 31 mile multi-loop trail ultramarathon on mostly single-track/double-track at the amazing Western Slopes of Massanutten Mountain, maintained by the Shenandoah Valley Bicycle Coalition. You will complete five 10k figure-eight loops. There is an aid station every 5k, where you can also pass by your drop bags for self-support.  The course has an elevation gain of  4000 ft (~800 ft of climbing per 10k loop). You will have ample time to complete the course with a generous 9 hour cutoff. We strive to create one of the best, and most runner-supported ultra race experiences in Virginia
