Since 2004, Thornhill Multisport has offered year around programs for master swimmers, open water swimmers and triathletes. Our goal is to bring people into the water, whether beginner or experiences, and to help them achieve their goals in Swimming.

Over the years, THOR has not only been amongst the top Masters Swim Clubs in Ontario, but our coaches have also trained swimmers who compete in triathlons, Open water swimming, Swimruns, and much more. Our swimmers have competed in swims around the world, including a Lake Ontario crossing, Triathlons from sprint to Ironman, and the World SwimRun Championships. Our endurance athletes compete throughout the year in events of all types.

We invite all swimmers who are looking for a great place to swim to come and join us.

Thornhill Multisport runs 2 core programs:

1. The Thornhill Masters Aquatic Club – our masters swim program where members range from beginner swimmers learning the basics of masters swimming experienced swimmers competing at all levels. This program offers a mix of endurance training, stroke correction and teaches our members the skills to succeed in competition.
2. Thornhill Enduroswim – Endurance training for open water swimmers, triathletes, and swimrun enthusiasts. Starting in September and running through to the end of June, our pool workouts focus on building endurance and the skills required to succeed in an open water situation, while over the summer months we offer a 3 time a week training program at Cherry Beach in Toronto.
