Geoff Duke
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. Despite the conditions, Geoff Duke riding the works Gilera set a time of 25 minutes and 41.0 seconds an average speed of 88.18 mph and led Ray Amm riding for Norton by 14 seconds on lap 1. On the second lap, Geoff Duke lapped in 26 minutes and 23 seconds at an average speed of 85.84 mph and Ray Amm lapped at an average speed of 86.49 to reduce the lead to just 2 seconds. 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" tactics on the slower corners. The leader, Geoff Duke, decided to refuel on lap 3. Ray Amm in second place went straight through without stopping and lapped in 25 minutes and 28 seconds at an average speed of 88.93 mph and now led Geoff Duke by 32 seconds. At the Windy Corner on lap 4, the visibility was down to 20 yards and a decision was made to stop the race because of the conditions. This allowed Ray Amm, due to refueling at the TT Grandstand on lap 4, to win the 1954 Senior TT Race in 1 hour, 42 minutes and 46.8 seconds at an average race speed of 88.12 mph. The controversial decision by race organisers to stop the 1954 Senior TT Race on lap 4, just as the weather started to improve, was protested by the Gilera management. This was on the grounds that the works Norton team were told of the decision allowing Ray Amm to lead the race on lap 3, but the official protest was rejected by the race organisers. 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.
