Three Rivers Marathon Swim
Point State Park, United States • 23 Aug 2025
The Three Rivers Marathon Swim is a unique 30K open water swimming event held in Pittsburgh, Pennsylvania, traversing the city's three rivers: the Ohio, Monongahela, and Allegheny. Starting at Point State Park, swimmers navigate out-and-back segments in each river, supported by powered escort boats and two kayakers per swimmer. The course features a mix of current-assisted and against-the-current swimming, with varying water conditions and an average temperature around 72°F. Limited to 12 solo swimmers, the event emphasizes safety with a strict 12-hour cutoff. Proceeds benefit the Forever Fund, supporting families facing infant cardiothoracic surgery at UPMC Children’s Hospital. Visit the organization's website for the most recent information.
