It was contested on a handicap basis over six laps of the 8.6 mile course, a total distance of 50 miles. The handicap format saw the slowest cars starting first and the fastest cars starting last.
The race was open to standard touring and sports cars, fitted with standard equipment and operating on standard first grade fuel. The only modifications permitted to the cars were the raising of the compression ratio and alterations to the suspension.
