Bruce Gordon, 49, of Denver, Colo., is a long-distance swimmer looking to do what has been done just 19 times before: cross the 26-mile Kaiwi Channel connecting the Hawaiian islands of Oahu and Molokai. To prepare for his historic crossing, he swam 18.5 miles in Lake Coeur d’Alene, Id., starting at Harrison and landing at Coeur d’Alene Beach. The swim began Friday at 8:20 a.m. and ended at 8:49 p.m. on Friday night. A handful of supporters and surprised beach goers were there to greet him as he stepped out of the water and onto the beach. “It was a big relief to get out of the water,” Gordon said. “I didn’t really know what was going to happen since I’d never gone that far. I finished without being too tired and I was very lucid, and that surprised me. I’m already anxious to be swimming again”/21Ten. More here.
