How far can a slot car go in 24 hours?   This has long been seen as the ultimate slot racing endurance challenge.   No doubt the original inspiration for 24 hour races came from the  Le Mans 24 hours, however  slot racers developed their own rules rather than just following the full size precedent.  When it comes to 24 hour World Records, to ensure a fair competition, there was seen to be a  needed some limitation following areas.

1 What type of car is used - Generally cars have to follow current racing regulations.

2 What type of track is used - The restrictions on corner radius etc. prevent the use of "speed bowl"  type circuits.

3 How much of the car can be replaced  -  This is a test of endurance for a car. Although some components can be replaced, replacing complete cars is most certainly not a permitted.

4 It has to be a race - Record attempts with just a single  car running are recorded but not recognized as race records.

The rules?

In the 1960s Duncan Laycock wrote the rules which have been the basis of 1/32 records ever since. (Link to Laycock Rules) In the early 1990s, a version of the "Laycock" rules adapted for HO (1/64) racing were agreed.  These rules were adopted by Guinness publishing as world record guidelines.

The EEC (European Endurance Championship) was a series of 1/24 races run each year for Group 12 powered 1/24 cars. The 1/24 flat track record was set in 1997 by a car to these EEC car standards.  Cars to current 1/24 open group 12 are eligible for this record

The rules for the outright record (most recently set in 2019) allowed  one chassis,  two motors and four bodies.  The outright  records have been set on  banked King tracks.
