Three Rivers Marathon Swim

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 embark on an out-and-back course with segments of approximately 10K each in the three rivers, facing varying currents and water conditions. The event features a mass start limited to 12 solo swimmers, each accompanied by two kayakers and supported by powered escort boats and safety personnel.

Water temperatures average around 72°F, and a strict 12-hour cutoff ensures swimmer safety. Proceeds benefit local families facing infant cardiothoracic surgery costs. Visit the organization's website for the most recent information.
