Itala driver Maurice Fabry started the fastest of the competitors; he covered the first kilometre in 43.4 seconds. Over the full distance of the lap Brasier's Baras was the quickest; his lap time of 52 minutes and 25.4 seconds (52:25.4) moved him up to third position on the road and into the lead overall. A mechanical problem caused Gabriel to lose control of his car at Saint-Calais; he regained control in time to avoid a serious accident but was forced to retire. Baras maintained his lead after the second lap, but fell back to second the next lap as Szisz took over the lead. As the day grew hotter the tar began to melt, which proved to be a greater problem than the dust; it was kicked up by the cars into the faces of the drivers and their mechanics, seeping past their goggles and inflaming their eyes. The Renault driver, J. Edmond, was particularly affected: his broken goggles allowed more tar to seep past and rendered him nearly blind. His attempts to change the goggles at a pit stop were rejected by officials on the grounds that equipment could not be replaced mid-race. Nor could another driver be substituted; he continued for two more laps before retiring.
