The first race, held on 14 April 1929, was won by William Grover-Williams (using the pseudonym "Williams"), driving a works Bugatti Type 35B. It was an invitation-only event, but not all of those invited decided to attend. The leading Maserati and Alfa Romeo drivers decided not to compete, but Bugatti was well represented. Mercedes sent their leading driver, Rudolf Caracciola. Starting fifteenth, Caracciola drove a fighting race, taking his SSK into the lead before wasting minutes on refuelling and a tyre change to finish second. Another driver who competed using a pseudonym was "Georges Philippe", the Baron Philippe de Rothschild. Chiron was unable to compete, having a prior commitment to compete in the Indianapolis 500.
