Only 11 starters made it to this Lombank round due to the clashing Shell Super Oil meeting the next day at Oulton Park.
As the flag dropped pole-sitter Roger Williamson’s March 713M took the lead on what was a very wet track from the Brabham BT35s of Colin Vandervell and Brendan McInerney, after 5 laps McInerney started to close in on Vandervell but then started to drop away again. After 10 laps Vandervell, who had been carrying out a lot of testing on the BT35, closed in on Williamson and for the rest of the race he harried the March unmercifully but although the Brabham was all over the March in the corners the Rowland was loosing out to the Holbay on the straights. At the finish Williamson held on to win by 0.6 seconds.
McInerney finished an untroubled third ahead of Ronald Rossi’s Brabham BT28 and Jose Ferreira in a similar car, Ferreira was still wearing a plaster cast as a result of his Silverstone shunt and had the additional handicap of a 10 second penalty.
