Summary of Marilyn's swimming achievements

I swam Lake Ontario the easy way (south to north) in 1983 and the hard way (north to south) in 1984, becoming the first person to have swum it in both directions.
I came "out of retirement" to swim the English Channel in 2011. I won the Van Audenaerde cup for the toughest endurance feat of the year because the winds peaked at 26 knots and the waves at over 3 meters and the water temp was only 17.5 deg. C. Lake Simcoe (Barrie to Orillia) had been a good training swim because the water was only 13 deg. C for the first 3 hours. In 2013, I was the oldest Canadian to swim the Catalina Strait in California. After swimming around Manhattan Island in 2014 (oldest Canadian), I became the first Canadian to complete the coveted Triple Crown of open water swimming (English Channel, Catalina strait and Manhattan).
In 2015, I was the first person to swim between three provinces: from Nova Scotia north to New Brunswick and across the Northumberland Strait to Prince Edward Island (34 km). In March 2016, I fulfilled a 3 year long dream, to be the first Canadian (and oldest woman) to swim across the icy (15-16 deg. C), treacherous Cook Strait between the South and North Islands of New Zealand. In August 2016, I swam across Cape Cod Bay, becoming only the 9th person and the first Canadian to swim this historic Pilgrim route across the shark infested swirling tidal waters.
In 2017, I became the oldest woman and first Canadian to swim the length of Lake Tahoe from California to Nevada (34 km). The major challenge was the elevation of the lake, at 6200 feet or 1897 m. In 2018, I fulfilled a 30 year dream to become the first person to swim across Whitefish Bay of Lake Superior (29 km, water 16.5 deg. C). Superior had been swum only twice before on a route in the western end of the lake. Later in 2018, I fulfilled another dream, of becoming the first Canadian to complete the California Triple Crown of swimming (Catalina Strait, Lake Tahoe and Santa Barbara Channel) by swimming the Santa Barbara Channel from Santa Cruz Island to Hollywood Beach, Oxnard, California on my second try after having been pulled out halfway due to a shark showing predatory behaviour (first Canadian, oldest woman).
I have also swum all 4 of the big Muskoka Lakes during 2013-2019.
