The first Thruxton endurance event was a 9-hour race and took place in 1955, it was organized by the Southampton and District Motorcycle Club (SDMCC) and took place at the Thruxton Circuit near Andover in Hampshire, 2 more 9 hour races followed in 1956 and 1957. These earlier 9 hour races resulted in the birth of the famous Thruxton 500 miler, the first taking place in 1958 and the last in 1973. The Thruxton 500 was an endurance race for production based road machines, covering 500 miles and ridden by a team of two riders per machine. There were 12 Thruxton 500 events that took place between 1958 and 1973, during that period however were 4 races where the 500 miler had to be run at 2 different circuits because of poor track conditions at Thruxton.〔Motor Cycle, 10 December 1964. p.987. ''Goss pulls out''. "''...news of the retirement of Neville Goss as secretary. Neville has, however, agreed to remain racing secretary and will continue to guide the 500-miler...he mentioned that arrangements had not been finalised regarding the future of the Thruxton circuit—especially the re-surfacing—but something would have to be done before next season''" Accessed 2014-04-01〕 The first rearranged 500 miler race was at Castle Combe〔Motor Cycle, 9 September 1965.

Official Site. ''Race Results'' Retrieved 2013-08-15〕 In the 1960s the Thruxton 500 race was very important to British motorcycle manufacturers as it was a 500-mile (800 km) test of their bikes which provided public-exposure. A win, or second and third places in the Thruxton 500 offered advertising opportunities and boosted sales, resulting in keen competition around Thruxton’s fast, flowing and demanding track. 4 other endurance events were held at Thruxton but not under the Thruxton 500 name, 2 Powerbike Internationals in 1974 and 1975 and 2 Grand Prix D' Endurance events in 1976 and 1977. 7 other endurance events were organized by the SDMMC at different circuits around the UK. Similar events were the Bemsee-organised Hutchinson 100〔Motor Cycle, 19 August 1965. p.2a.

"''The Honda CB450 is not yet regarded as a 'production' machine...the CSI decided not to change the rules—under which machines with two overhead camshafts are barred—as it would be 'unfair to make a chance in mid season'.''". Accessed 2013-08-21〕 Only one motorcycle race a year is now held at Thruxton - a round of the British Superbike Championship ==History== As with many World War II airfields, RAF Thruxton found a new role in the 1950s as a motorcycle racing circuit. Declared surplus to RAF requirements in 1946, the early track included both the runways and perimeter roads. An application was made in 1949 by the Southampton and District Motorcycle Club (SDMCC) to the Auto Cycle Union for approval of the circuit for motorcycle racing, with the result that an official Track Inspection took place on New Year's Day 1950. It was attended by Syd Lawton, Arthur Wheeler, Cyril Quantrill and a number of members of the SDMCC. The Track Certificate was granted and the first Thruxton motorcycle event took place on Easter Monday 1950 and organised by the SDMCC. The Bristol Motorcycle and Light Car Club organized a race event on 4 August 1952. In 1953 the East/West runway was cut out and the Western part of the perimeter track was included and the direction was changed to clockwise. In 1955 the SDMCC held their first motorcycle endurance race at the Thruxton Circuit near Andover in Hampshire, the start of a historic period for SDMCC. The Clerk of the Course for this first endurance event was the late Neville Goss, the race was for 9 hours and the motorcycles were ridden by a team of two riders per machine. 2 more 9 hour races followed in 1956 and 1957. 9 Hour results. 1955. W.E. Dow, and E.B.Crooks on a 500 BSA at 67.71 mph. 1956. W.E. Dow and K.W. James on a 350 BSA at 72.3 mph. 1957. F.Weber and R. Avery on a 350 BSA at 67.0 mph. No more 9 hour races, it’s now the start in 1958 of the famous Thruxton 500 races. Motorcycle racing continued on the bumpy wartime tarmac (which was slowly breaking) until 1965, when plans were agreed for a new track. The new layout ignored the original runways and followed the perimeter road with an added chicane and three tight corners in succession (named Campbell, Cobb and Segrave) which became referred to as the complex. In 1968 the British Automobile Racing Club took over the track and the longer circuit was used. Racing at Thruxton became famous for the endurance events for production motorcycles, and the Thruxton 500 in particular. The machines were supposed to be the same as could be bought, but most factories of the time invested in a racing team that invariably developed the motorcycles as much as possible. The Triumph factory first showed their ''Thruxton Bonneville'' – a hand-built, extra-specification race-styled machine at the 1964 Earls Court Show,〔Motor Cycle, 19 November 1964.
