Tanya Streeter , 2000
Having grown up in Grand Cayman, Tanya was perhaps destined for an aquatic career. But nobody could have guessed she would become the only woman in history to break a man’s world record in any sport, when she freedived to 525ft in 2002. Her achievements, totaling 10 world records, have raised the profile of freediving worldwide and her personality has changed its death-defying image. She’s a committed spokesperson for marine environmental groups and is an award-winning television presenter/host for the BBC and Animal Planet.
