The first heat was won easily by Clark, with team-mate Trevor Taylor in a comfortable second place, from Jack Brabham in third. All the other runners were lapped at least once. Brabham had led for most of the race but suffered fuel shortage problems and his engine cut out. The second heat saw a reverse of the first, with Brabham winning from Taylor and Clark, with just a few tenths of a second separating the two Lotus drivers.
