TheClypse Course describes a motor-cycle racing course used for theIsle of Man TT Races between 1954 and 1959.
The course is 10.92 mi (17.57 km) long[1] and is in the parish ofOnchan in theIsle of Man. The course uses two short sections of theSnaefell Mountain Course which includes the primaryA18 road betweenCronk-ny-Mona andCreg-ny-Baa used in the reverse direction. Also, the primary A18 Mountain Road betweenSignpost Corner andGovernor's Bridge. The highest point of the course is 856 ft (261 m) above sea level at Ballacarrooin Hill (Ordnance Surveygrid referenceSC 406 827). The name Clypse is probably a contraction from the Scandinavian wordKleppsstar ( Kleppr's farm) which gives the modern name of Clypse Beg and Clypse Mooar.[2]
The Clypse Course was a newstreet circuit for racing in the Isle of Man was used to re-introduce theUltra-Lightweight TT andSidecar TT Race for the1954 Isle of Man TT Races. To facilitate racing on the Clypse Course, during the winter of 1953/54 road widening occurs on the Mountain Course at Creg-na-Baa,Signpost Corner and the approach to Governor's Bridge. The re-introduction of the Sidecar TT Race for the 1954 Isle of Man TT Race was controversial as it was opposed by the motor-cycle manufacturers and also for the inclusion of the first female competitorInge Stoll at an Isle of Man TT race.[3]
TheLightweight TT Race was run on the Clypse Course for the first time in 1955 and continued until the 1959 race. The Clubman Races were run on the Clypse Course for 1955, then reverting to theSnaefell Mountain Course for the next year. The last year for racing on the Clypse Course was the1959 Isle of Man TT Race.
For 1960, the Lightweight, Ultra-Lightweight and Sidecar TT Races reverted to the Mountain Course.
The lap record for the Clypse Course is 8 Minutes and 4.2 seconds at an average speed of 80.22 mph (129.10 km/h) set byTarquinio Provini during the 1959 Lightweight TT Race.
The Clypse Course has not been used since 1959. Parts of the Clypse Course that are not part of theSnaefell Mountain Course have been used for cycle racing, Hill Climb events and Classic Car Racing. Parts of the Clypse Course which include the secondary road B12 Creg-na-Baa 'Back-Road' and the B20 Begoade Road are regularly used for theRally Isle of Man and the Manx Rally.
