Swim the Suck

The Tennessee River through the Gorge is a powerful, serpentine corridor that defines the landscape of southeastern Tennessee. Before the construction of the Hales Bar Dam in 1913, these waters were feared by rivermen for their violent navigational hazards—notorious stretches like the Kettle, the Skillet, the Pot, and the Deadman's Eddy, where the river's force was compressed into unpredictable, swirling currents. Today, the river flows with a different temperament, but it remains a rugged, untamed artery cutting through dense forest. As you swim the 10-mile course, you are moving through a 26-mile canyon that serves as a biological refuge, supporting over a thousand varieties of plants and providing critical habitat for protected species like the mountain skullcap.

A corridor of history and nature

Your path takes you past significant markers of the region's complex past. Near the mouth of Chickamauga Creek, you pass the Chickamauga Mound, a landmark dating back to 750 CE that remains the oldest visible human construction in the area. This river was also a decisive theater during the American Civil War; after the 1863 battles for control of the city’s rail hubs and arsenals, the river became the Union’s primary gateway into the Deep South. While you focus on your stroke, keep an eye on the shoreline for the entrance to Nickajack Cave, where a massive bat colony resides, monitored by regional biologists. As you navigate the river, you will also skirt the edges of Williams Island, a 450-acre wildlife sanctuary managed by the Tennessee River Gorge Trust that served as a hub for Native American tribes for over six centuries.

Race day logistics

Founded in 2010 by the Chattanooga Open Water Swimmers (C.O.W.S.), the race is a highly organized logistical operation. Because every solo swimmer must be accompanied by a personal pilot in a kayak, the entry fees—ranging from $445 to $640—account for the essential safety infrastructure, mandatory boat support, and shuttle services from the finish line back to the start. The event takes place on October 3, 2026, starting from the Suck Creek Boat Launch. The registration package is comprehensive, including a pre-swim dinner at the Waterhouse Pavilion, post-race meals, and commemorative gear. Whether you are swimming solo or as part of a two-person relay, the event requires strict adherence to pilot coordination to manage the river's remaining current dynamics.
