The Ulster Grand Prix was included as one of the races in the inaugural 1949 Grand Prix motorcycle racing season (now MotoGP), a place it held until 1971. It also counted for the Formula TT Championship between 1979 and 1990. The race has been held on three different circuits. The 20.5 mi (33.0 km) Old Clady circuit was used from 1922 until 1939 and included a notoriously bumpy 7 mi (11 km) straight.
