 BC lifeguard Jessie Lidstone-Harwitz is an experienced marathon swimmer. She has swum from Santa Cruz to Monterey, from Northern Ireland to Scotland, and now she's completed a swim here in Canada to raise money for the Life Saving Society's Swim to Survive program. This month, she swam Lake Ontario in 22 hours and 7 minutes. She says it's her longest freshwater swim yet. She told the CBC about the conditions.
