About This Race
The Grindstone Running Festival by UTMB delivers one of the most challenging trail running experiences on the East Coast. Set in the heart of Virginia's Shenandoah Valley, this highly technical course winds through the George Washington and Jefferson National Forests, testing runners across demanding ridges, peaks, and valleys of the Appalachian Mountains. Timed during peak fall foliage season, the race offers spectacular mountain views and diverse wildlife encounters as runners navigate miles of technical singletrack. The event serves as both a Western States Endurance Run qualifier and a UTMB World Series qualifier, drawing serious ultrarunners seeking entry into the sport's most prestigious events. The festival format includes multiple distances from 21K to 100 miles, making it accessible to runners building toward longer ultras while maintaining the technical challenge that has made Grindstone a respected fixture in the trail running community.
The 50K course covers technical terrain through the Shenandoah Valley's mountainous landscape, featuring sustained climbs and descents across ridgelines with 5,085 feet of elevation gain. Runners traverse singletrack trails through dense forest, navigate rocky technical sections, and experience panoramic views from Appalachian peaks.
