Old Dominion

The Old Dominion 100 Mile Endurance Run is a challenging ultramarathon held annually in Virginia, featuring a diverse course that includes various terrains such as pavement, gravel roads, and trails. Established in 1979, this event emphasizes tradition and community, being entirely volunteer-run without sponsorships. Participants face significant elevation changes, with 14,000 feet of gain, and must complete the race within 24 hours to earn a coveted silver buckle.

The event is part of the Grand Slam of Ultrarunning series and attracts runners seeking to test their endurance against a demanding course. The next race is scheduled for June 7, 2025. Visit the organization's website for the most recent information.
