Atlantic City Around the Island Swim
The Around the Island Swim (Around the Island Marathon Swim or the Around the Island (Absecon) Marathon Swim) in Atlantic City, New Jersey (U.S.A.) was a 22.5-mile (36.2 km) professional marathon swimming competition that attracted most of the world's fastest marathon swimmers from the 1950's to the 21st century.
It was a circumnavigation around Absecon Island on the Jersey Shore that demanded swimmers tackle the Atlantic Ocean, inlets with tidal flows, and back bay environments in the clockwise direction. The ocean temperatures varied from the 12-13ºC on a cold day to 25-28ºF in the back bay on a warm day. Ocean currents and tides are unpredictable and came from any direction.
Each swimmer was escorted by two certified South Jersey Beach Patrol Lifeguards as rowers in a surfboat.
