Ken came into motorsport entirely by accident, after being demobbed at the end of the war, he accepted a job at the RAC in Pall Mall, without any knowledge of the sport. Ken worked alongside Dean Delamont who introduced him to racing and he he quickly became acquainted with the Half-Litre Car Club and was made secretary in 1951. Ken made a very important contribution to the movement and to the development of racing at Brands Hatch, the Club's home.

Gregory is best know as Stirling Moss' manager, with whom he had a close relationship for several years but he began competing in 1950 when Cyril Kieft invited him to drive one of the original Kiefts at the inaugural Brands Hatch meeting. The car was not as quick as the Coopers but led to Kieft tackling 350cc and 500cc international records at Montlhery in November 1950, the driving team consisted of Moss, Gregory and John Neil. The team took 14 records.

Ken was instrumental in the persuading Cyril Kieft to sponsor, what became, the CK 51 the prototype being built by Ray Martin specifically for Stirling to drive.

Ken also raced a Cooper and later a JBS but his outings were always limited by his commitments to Moss, the Half-Litre Club and the RAC. Ken Gregory also managed Peter Collins, was a director of Brands Hatch, secretary of the British Racing & Sports Car Club as the HLCC became known, and co-founder of the British Racing Partnership with Alfred Moss, as a vehicle for Stirling to go racing.

The BRP team ran Cooper-Borgwards, a BRM (briefly), UDT-Laystall Lotus 24s and their own version of the Lotus 25. BRP then built a pair of unsuccessful Indianapolis cars for 1965 and eventually closed down in 1966 after a planned F1 project was scrapped. Ken also also had a successful publishing career, including his own biography.

With laurels for wining the Junior Championship race at Brands Hatch on 17th September 1950.
