Greenbrier River Trail Marathon & Half Marathon

The Greenbrier River Trail Marathon & Half Marathon takes place in Cass, West Virginia, on October 3, 2027, with a trail marathon (26.2 miles / 42.2 km) and a trail half marathon (13.1 miles / 21.1 km). Both races start together at 8 a.m.

A marathon run on a trail is not managed like its road equivalent: the softer surface is easier on the joints but slows the pace slightly, so the usual time benchmarks need adjusting. It is best to run by perceived effort and wear shoes suited to the terrain, with a little more grip than on pavement. The half marathon suits runners who want to try this type of surface before committing to the full distance. Either way, a few long runs on trails before race day are worth more than training exclusively on roads.
