Roads around the track were closed to the public at 5 am on the morning of the race. A draw took place among the thirteen teams to determine the starting order, and assign each team a number. Each of a team's three entries was assigned a letter, one of "A", "B", or "C". Two lines of cars formed behind the start line at Montfort: cars marked "A" in one line and cars marked "B" in the other. Cars assigned the letter "C" were the last away; they formed a single line at the side of the track so that any cars which had completed their first circuit of the track would be able to pass. Cars were dispatched at 90-second intervals, beginning at 6 am. Lorraine-Dietrich driver Fernand Gabriel (numbered "1A") was scheduled to be the first competitor to start, but he stalled on the line and could not restart his car before the FIAT of Vincenzo Lancia, who was next in line, drove away. Renault's lead driver, the Hungarian Ferenc Szisz, started next, and behind him Victor Hémery of Darracq, Paul Baras of Brasier, Camille Jenatzy of Mercedes, Louis Rigolly of Gobron-Brillié and Alessandro Cagno of Itala. Philippe Tavenaux of Grégoire, scheduled next, was unable to start; the only other non-starter was the sole Vulpes of Marius Barriaux, which was withdrawn before the race when it was found to be over the weight limit. The last of the thirty-two starters—the Clément-Bayard of "de la Touloubre", numbered "13C"—left the start line at 6:49:30 am.
