In Heat 6, Denmark's future triple World Champion Erik Gundersen set the 4 lap record of 66.8 seconds for the 345 metres (377 yards) long track when he defeated eventual 3rd placed rider Tommy Knudsen (Denmark), Jiří Štancl (Czechoslovakia) and Zenon Plech (Poland). As this was the final speedway meeting at Wembley it will forever be the track record.
