Which course hosted the reintroduced Sidecar TT in 1954?

The reintroduced Sidecar TT in 1954 was hosted by the Clypse Course.

The Clypse Course was a temporary street circuit on the Isle of Man, used from 1954 to 1959. It incorporated parts of the Mountain Course but followed a different layout, including sections near Onchan and Governor’s Bridge. Its creation allowed the Ultra-Lightweight TT and Sidecar TT to return to the programme after both races had been dropped because of poor entries.

The 1954 Sidecar TT covered 10 laps, or 107.90 miles. Eric Oliver and passenger Les Nutt won on a Norton outfit, averaging 68.87 mph. The race was limited to machines of up to 500cc, making it distinct from later non-championship sidecar categories.

A common mix-up is choosing the Snaefell Mountain Course, because that is the famous modern TT circuit and was used for many other races. In 1954, however, the Sidecar TT specifically used the Clypse Course.
