Silverstone Circuit 28th October 2006 - 57th 'Holly' Birkett Handicap Relay Race.
This race is a unique event in the world of motor racing and was originally conceived to give cars of differing performance the opportunity of competing on 'equal' terms in a long-distance race; the concept obviously worked and it has proved to be one of the most popular events in the UK.
The event is based upon a free relay system for teams of cars. Working on information provided and many years of experience, the handicappers decide upon which team they consider will complete the most laps within the 6 hours - this is the 'Scratch' team.
The remainder of the teams are given credit laps according to their estimated performance in comparison to the Scratch team and these credit laps are added to those actually completed.
Should the Safety Car be used, then the credit laps are proportionally adjusted. The results of the race can be affected by the tactics of the Team Manager just as easily as by the performance and reliability of the cars.
If one car in a team is significantly faster than the others, the handicappers may assume that that car will attempt to do more than its fair share of the racing; in that case there may be a limit placed upon the number of laps which that particular car is permitted to complete. If that car does more than its permitted laps, the team faces disqualification from the handicap results, or can opt out of the handicap and simply race for the overall win. During the length of the race, cars will break down out on the circuit. Team Manager has to decide by how long a car can be 'missing' before sending out a replacement. If the 'missing' car has simply spun and rejoined the race, no laps are scored whilst two cars from the same team are racing.
Results are issued at 60 minute intervals to show the current placings both on handicap and actual.
