[edit] History
The Clypse Course was a new race circuit for racing in the Isle of Man was used to re-introduce the Ultra-Lightweight TT and Sidecar TT Race for the 1954 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-inroduction 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 competitor [[Inge Stol] at a Isle of Man TT race.[2]
The Lightweight TT Race was run on the Clypse Course for the first time in 1955 and continued until the 1959 race. The Clubman Races where run on the Clypse Course for 1955, the reverting back to the Snaefell mountain course for the next year. The last year for racing on the Clypse Course was the 1959 Isle of Man TT Race. For 1960, the Lightweight, Ultra-Lightweight and Sidecar TT Races reverted back to the Mountain Course.
