Trans Tahoe Relay
Trans Tahoe Relay is an 10-mile masters relay swim organized in Lake Tahoe by the Olympic Club of San Francisco. The 6-person relay annuals draws hundreds of teams from around the world and is one of America's Top 50 Open Water Swims. The unique open water swimming event started when Olympic Club members decided to challenge each other to a team race across Lake Tahoe in 1976. Soon after, other clubs were invited to join this annual "Invitational Relay" event. In 2011, the race attracted over 1,134 competitors. Promoting team camaraderie and spirited competition between swimming clubs and other groups and organizations, it is now seen as a landmark of open water events.
