Grindstone Running Festival by Utmb

Grindstone Running Festival by UTMB is an East Coast trail event staged at Natural Chimneys Park in Virginia, just west of the Shenandoah Valley. Runners choose from four distances: 100M, 100K, 50K, and 21K, with a highly technical course that climbs ridges and peaks through the George Washington and Jefferson National Forests. Expect rugged terrain set against peak fall foliage, mountain views, sunrises, and sunsets that mark the Shenandoah Valley.

The festival is a dual qualifier for UTMB World Series Finals and Western States Endurance Run, with Running Stones earned by finishers. UTMB Cares US supports environmental initiatives tied to the race community. Visit the organization's website for the most recent information.
