The fastest time to continuously swim the entire length of Okanagan Lake is 40 hrs 57 min 11 sec and was achieved by Adam Ellenstein (USA), who covered a distance of 106.6 km (66.24 mi) wearing a wetsuit and swimming north to south between 25 - 26 July 2016.

Adam remained in the water at all times during this epic swim, receiving food and drink from a support team who rowed either side of him in two kayaks and passed him the rations as needed. Adam swam 106.6 km (66.24 mi) by GPS, using a wetsuit and neoprene cap for the duration of the swim.

Adam partnered with the Davis Phinney Foundation to attempt this record, which he undertook in honor of his Aunt Susan who was diagnosed with Parkinson's disease in the fall of 2015.

Adam is the first person to continuously swim the entire length of the lake from Vernon to Penticon, although in 1958 Canadian BC Sports Hall of Fame inductee Ann Meraw had swam 88.51 km (54.68 mi) without wetsuit in 32 hours 12 minutes. This was the longest distance by the female swimmer, who had already swum the lake previously, achieving 42 miles in 25 hours 1 minute in 1956 and 32 miles in 16 hours 14 minutes in 1957.
