Three members of the Polar Bear Club in Atlantic City, New Jersey participated in a swimming marathon on February 24, 1957. It did not go well.
The rules were simple. First, each man had to swim one mile in the 52° F (11.1 º C) frigid water. Next, each had to stand near shore in water up to their necks. The one who stayed in the water the longest won the contest. The award was $200 (approximately $1800 today), which was kicked in by tavern owner Sol Bogotin.
At the 55-minute mark, the body of 36-year-old Lucious Marcel suddenly stiffened up and he was taken by ambulance to a nearby hospital. Six minutes later, 26-year-old Jack Morris did the same. Finally, four minutes after this, 23-year-old Al Black was able to walk water on his own and win the prize. An unnamed dog also wanted into the water to join in and first aid needed to be administered.
The two hospitalized men were treated for exposure and muscle contraction, while Al Black was just fine.
