Kimberley Chambers is a marathon open water swimmer from New Zealand. After a freak accident left Kim Chambers with a mere one-percent chance of walking unassisted again. Determined to prove the doctors wrong, Kim spent two years rehabilitating her leg and has now regained almost full functionality. She began swimming again as part of her rehabilitation, and has since become the sixth person in the world to complete the Ocean’s Seven swimming challenge. In 2015, she became the first woman to swim from the Farallon Islands to the Golden Gate Bridge – a distance of about 30 miles. Many consider it to be the hardest marathon swim in the world.
