LAKE TITICACA, Bolivia (Reuters) - Andrea Oriana, an Italian former Olympic swimmer, has set a new record on the high-altitude and chilly Lake Titicaca, the world's highest navigable lake that is surrounded by Andean mountain ranges between Bolivia and Peru.
The 47-year-old swam across 20 kilometers (12.43 miles) of the lake without a wetsuit in a total 5 hours and 33 minutes, breaking the previous record for distance swum on the lake at his third attempt, despite bracing waters and thin air at 3,812 meters (12,506 feet) above sea level.
