Margaret Park from Canada was inducted in the International Marathon Swimming Hall of Fame in 2000. She swam in the 1960s with three successful marathon swimming brothers. Brother Tom is also an Honour Swimmer in the International Marathon Swimming Hall of Fame.
In the 10-mile Hamilton Marathon Swim, 41 swimmers started and only 9 finished: Margaret was the first woman and two of her brothers (Tom Park and George Park) also finished. Her other major swims were 28 miles in the Saguenay River (twice - once in each direction), 10-mile Quebec City swim, Lac Simone and Lac St. Clair. In a two-person relay race at the Expo 67 Montreal in Canada, Margaret was the only woman and paired with a stranger. Her teammate vanished after the second hour and Margaret completed the remainder of the 24 hours solo.
She once completed a rescue of a 2-year-old baby.
