Revenge of the Penguins Potomac, MD   Sep 14, 2025

The Revenge of the Penguins starts & finishes on the C&O Canal Towpath, Carderock Recreation Area, Clara Barton Parkway between Mile post 10 and 11. This unique out-and-back course runs through one of the area’s first environmentally-protected zones, dating back to the 1830s. It’s flat, shady, tree-lined, with scenic riverside vistas – the course you always dreamed about! Watch for deer and other wildlife at dawn.

The C&O Canal for its entire 184.5-mile length is a swath of green amidst urban development. The race course is a narrow (12-foot) wide unpaved trail, entirely flat, and runs past 150-year-old locks and gatehouses. Water and aid stations will be offered at the locks roughly every two miles.

This is a low-key, low-stress practice race for anyone training for a marathon, half marathon, or for anyone that just wants the challenge. Course support provided.
