The course uses two short sections of the Snaefell Mountain Course which includes the primary A18 road between Cronk-ny-Mona and Creg-ny-Baa used in the reverse direction.

The highest point of the course is 856 ft (261 m) above sea level at Ballacarrooin Hill (Ordnance Survey grid reference SC 406 827).

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 Clubman Races were run on the Clypse Course for 1955, then reverting to the Snaefell Mountain Course for the next year.

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 by Tarquinio Provini during the 1959 Lightweight TT Race.
