What does it really feel like to swim under the Golden Gate Bridge, cross an ocean channel at night, or share the water with whales? This week, I’m joined by marathon swimmer Lauren Lesyna, who takes us inside the fascinating world of open water swimming.
I quiz Lauren on the female history of San Francisco’s Dolphin Club, the world’s longest unassisted swims, and myths about jellyfish stings — while she shares incredible stories from her own adventures.
Lauren has tackled some of the world’s most iconic swims, from the English Channel and North Channel, to California classics like Catalina Channel, Angel Island, and Lake Tahoe, all the way to the Strait of Gibraltar. Along the way, she’s collected stories about whales, sea lions, bioluminescence, jellyfish stings, and the incredible team effort it takes to survive hours in the open ocean.
From history-making swims to jellyfish stings in the shower (yes, really), Lauren brings epic stories, humor, and insights that will make you see the Bay in a whole new way.
In this episode, we cover:
