Hosted by the District of Columbia Aquatics Club and the Potomac Riverkeeper Network, this August 1, 2026 open water swim at National Harbor lets you choose between 2.5k and 5k distances while supporting two great causes. Your participation helps fund PRKN's clean water initiatives and DCAC's mission to advance swimming and fitness within the LGBTQIA+ community and their allies. Join fellow swimmers in this beloved annual fundraiser that continues a proud tradition of celebrating open water swimming in local waters!
