### Instruction: What is the Trans Tahoe Relay?
### Response: Each year there is a race held to swim across Lake Tahoe. The race was created and is still sponsored by The Olympic Club of San Francisco. Teams are created and entered from across the globe but primarily North America. The format of the race is a six person relay; all male, all female. or half male/female. Starting on the Nevada side of the lake each member of the team swims for 30 minutes following the team's boat. After each of the swimmers has completed the 30 minute rotation the swimmers then rotate again every 10 minutes. This is done is sequence until the team reach the other side of the lake in California. The swimmers need to touch one-another when rotating between swimmers and there are no wetsuits or fins allowed.
