St John Horsfall finished sixth but chose not to start the final due to a stiff piston.

Reg Parnell led the first lap but Ascari retook the lead and steadily pulled away.

The race complexion changed in the middle phase: heavy rain began to fall, which better suited Parnell, and at the same time Ascari developed minor engine issues.

Geoffrey Crossley finished sixth; he handed his Alta over to George Abecassis for the final.

Farina and Parnell had jumped the start and were handed a one-minute post-race time penalty after respectively finishing second and fifth on the road.
