| Hillclimbing | ||||||||||||
| Hillclimbing is a branch of motorsport in which drivers compete against the clock to complete an uphill course.
The challenge of Speed Hillclimbing is to drive the course in the shortest possible time. The faster drivers are those who can get the car off the start quickly, the first 64 feet often takes as little as two seconds, and then find the quickest and smoothest lines through each corner. It is one of the oldest forms of
motorsport. Cars are grouped in to classes at each event. Cars are called down to the start in class order. Where a car is shared by another driver, the second driver (their numbers will start with a 7 or 9), will go down to the start in the batch before the other driver. The entries are divided into classes, so that similar cars compete against each other. Each driver not only competes in his or her own race against the clock, but also against other drivers in cars of similar performance. Each car carries a small vertical blade at the front called a timing strut. As a car approaches the start, the marshals line the car up immediately behind the timing beam. A chock behind the rear wheel keeps the car in the right position. When the driver is given the green light, they start in their own time. As the car moves forward it breaks the light beam and starts the electronic timing equipment. At the finish line there is another light beam that stops the digital timing equipment for that driver's run. In addition to the start and finish timing beams , there are usually other beams that allow the driver to see their ‘split' times at given points on the course after their run. Cars and Motorsport forum members often attend events at Harewood Hill. Details of other venues can be found on our Links page.
