New Zealander, Kim Chambers charts her improbable path to becoming one of the world's most accomplished open water swimmers.
After an injury to her leg, medical experts told her she had a one per cent chance of walking unassisted again.
She she out set to prove them wrong.
This year, in August, she became the first woman to finish what is known as the world's most difficult swim, from the Farallon Islands to San Francisco, through shark-inhabited waters.
The swim, took 17 hours and 12 minutes and had been completed by four men, but she was the first woman to accomplish it.
While Chambers took the swim very seriously, and took many precautions to ensure her safety, she says she "likes pushing the envelope".
She was just just nominated for the 2105 World Open Water Swimming Association Performance of the Year and a documentary is being made about her:
