In early June, Ben Lecomte will enter the waters off Choshi Marina Beach in Chiba Prefecture to begin a 10,000-km (5,400-nautical-mile) swim across the Pacific Ocean that seeks to shine a light on ocean pollution and plastic contamination, and put Lecomte into the history books as the first person to swim the Pacific.

※I*ve been working on it for the last seven years,§ says Lecomte in advance of his departure. ※So I feel like a tiger in a cage, I*m ready to go.§

Born in Paris, Lecomte, 50, is no stranger to the challenge of endurance swimming. In 1998, he became the first person to swim the Atlantic Ocean without a kickboard, a 5,980-km journey that took him 73 days.
