Founders Half Marathon

Founders Half Marathon is a Snowball Series running event held in Potomac, Maryland, at Carderock Recreation Area. It features a USATF-certified, out-and-back 13.1-mile course along the C&O Canal Towpath, with two water stops (Lock 10 and Lock 6) along the route. It is touted as the lowest-priced half-marathon in America and is Race 2 of the DC Road Runners Snowball Series, honoring the club’s founders.

The event emphasizes quality support and a casual atmosphere, offering a post-race breakfast, but no T-shirts or medals. Online registration only; non-members pay a small fee.
