About the Bull Run Run 50 Miler
The Bull Run Run is one of the oldest 50-mile races in the country, put on by the Virginia Happy Trails Running Club. It is based at Hemlock Overlook Regional Park in Clifton and its course follows Bull Run, past the site of the first battle of July 1861.
The modest entry fee, accessible course and 13-hour limit make it a common first 50 miler. Entry is capped at 300 on a first-come basis with a waitlist, and the race offers equal podiums and awards.
