Marathon Swim
Marathon swimming — the English Channel (21 miles), Manhattan Island (28.5 miles), Strait of Gibraltar — demands months of cold-water training, extreme cardiovascular endurance, and the mental fortitude to swim for 10-20+ hours. 45% of Channel swimmers are over 40. No wetsuit allowed on an official English Channel crossing.
