Swim Across America - Baltimore

The rhythmic pull of your stroke carries you through the calm waters of Redhouse Cove, where the horizon reveals the industrial scale of the Sparrows Point steel complex. This massive manufacturing footprint dominates the view, a stark contrast to the natural quiet of the shoreline. As you push further into the Patapsco River, the jagged cluster of White Rocks emerges from the surface, serving as a navigational marker for those tackling the longer distance.

Historical currents and defense

Swimming here means crossing a corridor once guarded by the Endicott Period coastal forts, a strategic network designed to shield the Baltimore harbor during the late 19th century. Near the entrance to the bay, you pass the remains of Battery Hartshorne, where disappearing carriage guns were once mounted to command these exact shipping lanes. The echoes of this military history remain etched into the shoreline, visible from the water as you glide past the preserved stone structure of Hancock's Resolution, an 18th-century farmhouse that stands as an anchor to the region's agricultural past.

Race day and logistics

Since 2010, the Baltimore Open Water Swim has gathered swimmers at High Tide Farm to support research at the Sidney Kimmel Comprehensive Cancer Center. The event offers one-mile and three-mile distances, with entry fees ranging from 50 to 200 USD depending on the registration window. Because the event takes place in late September, conditions are variable; while wetsuits are optional in the 65-75 range, they become mandatory if the water falls below 67. The course is designed for accessibility, relying on a dedicated fleet of water safety volunteers in kayaks and SUPs to monitor the lanes. For those seeking a different challenge in the same region, the Rev3 Mighty Matapeake takes place just weeks later, offering a distinct contrast to the protected cove environment found here in Pasadena.
