Organized by the Junior Car Club the
High-Speed Reliability Trial was held at Brooklands on July 4, 1931. There is a minimum
speed for each class of car, and reliability over a determined distance is the test. Cars
use part of the track, turn off into the paddock road, then follow a road circuit down the
steep test hill onto the track again. Most competitors turn the event into an unofficial
race, and the hairpin bend always produces some lurid skidding.
