The Shelsley Walsh Speed Hill Climb is a hillclimb in Shelsley Walsh, Worcestershire, England, organised by the Midland Automobile Club. It is one of the oldest motorsport events in the world, and is in fact the oldest to have been staged continuously (wartime excepted) on its original course, first having been run in 1905. On that first occasion, the course was 992 yards (907 m) in length, but in 1907 it was standardised at 1000 yards (914 m), the length it remains today.
Shelsley Walsh is a notably steep course by the standards of today's hillclimbs. It rises 328 feet (100 m) during its length, for an average gradient of 1 in 9.14 (10.9%), with the steepest section being as much as 1 in 6.24 (16%). This makes Shelsley a hill on which power is important, and on which the gap in times between the most powerful cars and the rest is greater than at many other venues. It is also narrow, being no more than 12 feet (3.66 m) wide at some points.
