He became successful on track as well as road. At Brooklands he won both the solo and the sidecar 200-mile events on the notoriously rugged outer circuit. In 1929 he raced up Switzerland's Klausen Hill Climb to win the 350cc class at record speed, riding the Marchant designed Motosacoche. On the European mainland and in Northern Ireland he had many Grand Prix victories. On three occasions in the inter-war period he became European champion, twice in the 350cc class (1928 and 1935) and once in the 500cc class (1928). He also became the holder of numerous motorcycle world records taken in 1930 at Arpajon and Montlhéry aboard the Belgian FN designed by Dougal Marchant. Earlier, at Brooklands in 1926, he broke the 200-mile world records for all classes up to and including 1000cc on his 350cc Rex Acme. On the same day he took the prestigious classic hour record for solo 500cc machines at 91.20 mph on a 350cc machine (Rex Acme-Blackburne). The only time this has been done.
