 The 20.5-mile "Old Clady circuit" was used from 1922 until 1939 and included a notoriously bumpy 7-mile straight.It also ran across part of the grass runway at RAF Aldergrove and for the first two years of its existence the pits were on the Seven Mile Straight, by Loanends Primary School.In 1926 the 500cc race was won by Graham Walker on a Sunbeam.
