Malcolm Ernest Uphill (15 April 1935 – 15 August 1999)[1] was a Welsh professional motorcycle racer.

[2] Uphill was the first competitor in the Isle of Man Tourist Trophy races to achieve a 100 mph average lap speed on a production motorcycle.

[3][4] A native of Caerphilly, Wales, Uphill later lived at Heol, Trecastle and was educated at Twyn Secondary Modern School.

[2] In 1969, he teamed with Percy Tait to win the Thruxton 500 endurance race for production (road-based) machines and at the 1969 Isle of Man TT, Uphill won the 750 Production class on a Triumph Bonneville with a 100 mph lap, which prompted renaming of the Dunlop K81 motorcycle tyre as the TT100.

[3] In 2011 a pub named The Malcolm Uphill was opened by Wetherspoons in Caerphilly town centre,[10] and in 2013, following local fundraising, a bronze plaque dedicated to Uphill's memory was installed on a wall close to the pub location at Station Terrace.
