Great Auclum National Speed Hill Climb was a motorcar course close to Burghfield Common in the English county of Berkshire.
It was based in the grounds of a large country house, formerly owned by a family connected to Huntley and Palmer – the famous biscuit manufacturers at nearby Reading, Berkshire. The hill climb was organised by the Hants and Berks Motor Club as a National Speed Hill Climb. This was part of the RAC British Hill Climb Championship, and at 440 yards (400 m) long it was the shortest of events in the Championship. The course travelled nearly as far downhill as it did up, with a finish almost level with the start. Motor Sport reported : "The ¼-mile course embraces two sharp corners, one banked, and a twisty section, so that a premium is set on initial acceleration and low-speed cornering."
Prior to World War Two at least one event took place at Burghfield, as the event was then known. In 1939 Motor Sport listed a forthcoming event: 27 May 1939, Sporting O.D.C. Speed event, Burghfield, which was cancelled. An event took place in June organised by the Frazer-Nash and Frazer-Nash B.M.W. C.C. and Sporting O.D.C. "The postponed speed hill-climb up the private drive of Neil Gardner's (sic ) house at Burghfield Common happened on June 24th, complete with adjacent funfair and Lord Nuffield to present the prizes." P.W. Neale set fastest time of the day in 27.0 secs "winning the 2-litre class from Fane's B.M.W."
Racing resumed in 1947 when: "Salvadori's monoposto Alfa-Romeo won its class in 25.2 sec., but couldn't be extended, and it was L.J.D. Bartlett's home-brewed Mercury Special which made f.t.d. in 23.5 sec." The following year Ken Wharton's Wharton Special "beautifully crisp and fearlessly handled, made f.t.d. in 23.34 sec., beating Stirling Moss (23.46 sec.), who drove absolutely superbly getting into third gear in his Cooper 500,..."
The last event was held in 1974 and the site has now been re-developed for housing. However the course itself is still there as it was the rear drive to Great Auclum house, which has now been redeveloped. The track is in a poor state of repair and very overgrown.
