The Triple Crown of Open Water Swimming

The Triple Crown of Open Water Swimming is an insane triathlon challenge. It's so unbelievable! This challenge involves three open water swim races. Namely, the Great British Swim, the English Channel Swim and the Manhattan Island Marathon Swim. These swims demand a lot of strength and courage. Completing all three swims in one year is a real test for any triathlete.

We'll explain why it's so hard and why it's considered the most difficult triathlon:


Open water swimming is widely known as the most extreme type of swimming. The bravest athletes take on the ‘Triple Crown' to prove their skill and endurance. It's a challenge of three iconic swims in large bodies of water.

The Triple Crown includes: English Channel (England/France), Manhattan Island (New York City/USA), and Catalina Island (California/USA). Each swim is an incredible feat of physical, psychological and logistical strength. It's one of three open water triathlons for courageous swimmers.

The other two open water triathlons include: Cook Strait (between North and South Island of New Zealand) and Tsugaru Strait (between Honshu and Hokkaido of Japan). Swimmers must brave colder waters and bigger waves in these cases, making it even more challenging than the Triple Crown!

Course Description

The Triple Crown of Open Water Swimming is a 113-mile epic journey that takes place in three iconic locations: the English Channel, Catalina Channel off the coast of California, and the Molokai Channel in Hawaii.

The English Channel swim is 22 miles from Shakespeare Beach, England to Wissant Beach, France. Swimmers brave strong currents and tides across one of the busiest shipping channels in the world. The route goes north to Cap Gris Nez, then southwest towards France.

The Catalina Channel crossing is 20 miles from Santa Catalina Island to Point Vicente Lighthouse near Los Angeles. Blue waters, favorable tides, and warm temperatures welcome swimmers. But they have to compete with the large seal colonies in the kelp beds!

The Molokai Channel swim is a 71-mile challenge between Oahu and Molokai Islands in Hawaii. It is nicknamed “the Everest” of swimming events. Tough tides and winds make it difficult. Plus, jellyfish blooms! Swimmers need to bring their own refreshments, since it can take up to 30 hours to complete.
