Who's going to Old Dominion 100 Mile Endurance Run?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The race

What this one is

The Old Dominion 100 is a 100-mile loop from the Shenandoah County Fairgrounds in Woodstock, Virginia, first run in 1979 and held on the first weekend in June. It leaves town through historic Woodstock, climbs into the Massanutten Mountains and circles Fort Valley on pavement, gravel forest roads, ATV trails and singletrack, with about 14,000 feet of gain. The start is 4 a.m. Runners who come in under 24 hours earn a sterling silver buckle, and there are 28 hours to finish. The race puts it as you, the clock, and the course, and it is run entirely by volunteers with no sponsors.

The run was started in 1979 by Pat and Wayne Botts, as a running division of the Old Dominion 100 Mile Ride, to give East Coast runners a chance to cover 100 miles in under 24 hours. In 1979 and 1980 it began and ended at Morven Park in Leesburg, Virginia, and 45 runners paid a $25 entry fee for the first one. It moved to Front Royal in 1981 and to Fort Valley in 1992. Tom Green's finish here in 1986 was the first leg of the first Grand Slam of Ultrarunning. The run separated from the horse ride in 1991, and the limits were set then to 24 hours for a buckle and 28 hours to finish. The race took a sabbatical year in 2002 and was cancelled in 2020, and it rejoined the Grand Slam in 2017. Eric Clifton's 15:10 from 1992 and Janice Anderson's 18:25:48 from 1997 are both still the course records.

Pacer rules
Safety runners are allowed from mile 75 (Elizabeth Furnace aid station) to mile 86 (Veach West aid station). They are there to keep the runner safe, not to help. Safety runners arrange their own transportation, and the race does not provide volunteer safety runners. olddominionrun.com
