About

The Old Dominion 100 Mile Endurance Run has crossed Virginia's mountain and countryside trails since 1979, starting at the Shenandoah County Fairground in Woodstock. It is one of the sport's oldest 100-milers and part of the historic Grand Slam of Ultrarunning, with a 28-hour cutoff and a silver buckle for sub-24-hour finishers.
