One Lap of America

The Brock Yates' One Lap of America is an annual motorsports event in the United States that has been held since 1984. It is the successor to the Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash, an underground auto race of the 1970s.

The original premise for both was to drive cross-country, but One Lap of America now respects speed limits, and has become a set of time trials at racetracks around the country, with overnight road trips between tracks. A minimum of two drivers are required. Cars must be street-legal and run one set of street tires the entire event.

Both events are the creation of automotive journalist Brock Yates. One Lap of America is currently sponsored by Tire Rack and organized by Brock Yates, Jr.
