100th Red Bull Cliff Diving World Series stop held in Boston, featuring US's only competition, with athletes performing leaps up to 90 feet into Boston Harbor.

Cliff divers compete at Boston's Institute of Contemporary Art in the Red Bull Cliff Diving World Series' 100th stop, leaping from up to 90 feet into Boston Harbor. The Boston event is the only US stop in the series, which concludes in Sydney, Australia in November. Cliff diving attracts athletes who train hard to master leaps, somersaults, twists and entries in potentially frigid waters.
