It had been the Scottish Clark whom had taken pole in qualifying, and proceeded to lead away from the grid, only to have Englishman Hill take the lead after a few laps. Their physical battle ended on the twentieth lap with Clark in the lead, before both exchanged record setting laps to pull further and further ahead. They lapped the entire field before the ninetieth lap, with the two only easing off once Bruce McLaren, running in third, had also been put a lap behind.
