Origins -

The race was originally planned to be a three-year event awarded the Rudge-Whitworth Triennial Cup, with a winner being declared by the car that could go the farthest distance over three consecutive 24-hour races. This idea was abandoned in 1928. From then on, overall winners were declared for each single year depending on who covered the farthest distance by the time 24 hours were up. Pictured is the 1923 program cover.

Many injured -
