Hall of Fame marathon swimmer Marilyn Korzekwa is planning a July swim across Lake Nipissing in July to raise money for a local charity.
The swim of approximately 28 km, will be done without a wetsuit and without any rest.
It has only been done once before before and is sanctioned by Solo Swims of Ontario.
Korzekwa has an impressive resume.
She has done some difficult swims including Lake Ontario in1984, the English Channel in 2011, and around Manhattan in 2014.
She was the first person to have completed Lake Ontario swims from both south-to-north and north-to-south on September 1-2, 1983 and August 17-18, 1984
