From the Organizer
Our race brings together community members, outdoor enthusiasts, and river supporters to advance the Potomac Riverkeeper Network’s mission to protect the right to clean water for all. Proceeds benefit PRKN’s work to stop pollution, make drinking water safe, protect healthy river habitats, and enhance the use and enjoyment of the Potomac and Shenandoah watersheds. What makes this event special is its celebration of our shared connection to these rivers—uniting people who live, work, and recreate in the watershed to take action for clean water now and for future generations.
