From Openwaterpedia
Christine Cossette was inducted in the International Marathon Swimming Hall of Fame in 1982 as an Honour Swimmer. In 1984, the Canadian professional marathon swimmer became the first person to complete a 64K (39.7-mile) double-crossing of lac St-Jean in Quebec, Canada in 18 hours and 27 minutes. After completing the first leg in 9 hours and 29 minutes, she swam the second leg in 8 hours and 59 minutes.
Her unprecedented two-way crossing led to an annual double-crossing Traversee Internationale du Lac St-Jean from 1985 to 1989.
