The 1954 Senior TT Race was stopped at half distance due to the weather conditions on the Mountain Section of the course.

[2] The new 10 lap (107.90 miles) Sidecar TT held on the Clypse Course was led from start to finish by Eric Oliver and passenger Les Nutt riding a Norton outfit with a "dust-bin"[3] fairing at an average speed of 68.87 mph.

The Norton outfit of Bill Boddice/J.Pirie hit a bank at Creg-ny-Baa and flipped over on lap 7, but continued on to finish the race in 6th place.

[5] In deteriorating weather conditions and with reduced visibility on the Mountain Section of the course the 1954 Senior TT Race was held after a short delay and started at midday.

[7] Further heavy rain and low cloud on the Mountain Section reduced speed further and the conditions caused John Grace and Ted Frend to retire at the TT Grandstand on lap 2 and Ray Amm used "feet-down"[4] tactics on the slower corners.

[8] During lap 1 of the 1954 Senior TT Race, Simon Sandys-Winsch riding a Junior Velocette crashed at the Highlander and died in hospital a few days later.
