Lisa Cowling is a South African extreme open water swimmer who won the 2012 Deep Blue Invitational Swim.
Deep Blue Invitational Swim
The Deep Blue is considered by many to be the toughest swim in South Africa outside of a Robben Island crossing. 30 of South Africa's most accomplished extreme swimmers are invited to swim 10 km at Shelley Point in the cold waters near St Helena Bay. 14 took to the waters, but only 7 finished with Cowling in first in 2 hours 24 minutes. The water temperatures ranged between 10.5–13°C.
