More than 1,200 swimmers are expected to take the plunge in Kelowna this weekend for one of Canada’s largest and longest-running open-water swimming events.

The 78th edition of the Across the Lake Swim Kelowna takes place Saturday, July 18, offering participants the choice of a 1.5-kilometre or 2.1-km point-to-point swim across Okanagan Lake.
Swimmers will start near the old ferry docks in West Kelowna before making their way across the lake to Hot Sands Beach in Kelowna’s City Park.

The annual event began in 1949 as part of the former Kelowna Regatta. It has since grown from roughly 200 participants to more than 1,200 swimmers and is described by organizers as the largest and longest continuously running open-water swim event in Canada.

Registration was still open as of Thursday, July 16, but swimmers do not have much time left to secure a spot. Organizers said registration closes at midnight tonight.

Younger swimmers can also participate in the free Kids Shore Splash at City Park on July 18. The shoreline event offers children between five and 12 years old a choice of a 25-metre or 50-metre swim.
