The RCP Tiburon Mile was envisioned and started by Bob Placak and is a 1 nautical mile cold-water swim from Angel Island in San Francisco Bay to the city of Tiburon in California, U.S.A. It is the most competitive open water swim in the world that pits Olympic pool swimming medalists against the fastest open water swimmers in the world. It offers a winner-take-all cash prize of US$10,000 for the fastest male and female. About 50% of the competitors use wetsuits. It is one of the World's Top 100 Open Water Swims and America's Top 100 Open Water Swims.
