The VLN endurance racing championship is each year made up of ten races at the Nürburgring. The competitions are organised in conformity with the FIA International Sporting Code, the DMSB Event and Circuit Prescriptions, the DMSB Environmental Prescriptions, the Anti Doping Regulations of the National Anti Doping Agency /NADA) and the VLN Sporting Regulations.
The teams must submit their entries to the various events in order to enter driver, car and competitor. The entry form including all the required documents are checked on-site before the start of each event at the administrative checks.
The timed practice takes place on Saturday morning of the race weekend and runs normally over the distance of 90 minutes. Due to the distance of almost 25 kilometres of the track, the drivers have the possibility to return to the Line after one lap over the short version of the Grand Prix Circuit in order to then start their timed lap on the complete circuit.
The participating cars are divided into three starting groups, according to their classes. The positions on the starting grids, which are set up about 80 minutes after the end of the timed practice, within these groups are determined on basis of the practice times. After a formation lap over the complete circuit, there will be a rolling start. The gap between each of the three starting groups is three minutes and this time will be taken into consideration when the final results are prepared.
During the race, the teams may come to their pits in order to refuel, to change tyres and drivers and to carry out any necessary repairs on their cars. The number of pit stops is not limited.
When the race distance of four or six hours has elapsed, the race leader will receive the chequered flag. The winner is the team which has covered the greatest number of laps at the moment the end-of-race signal is given. In the case of an equal number of laps, the shorter overall driving time will decide.
In the case of certain incidents, Race Control may be compelled to interrupt or stop the race by showing the red flag. In the first case, the race may be restarted and the two parts of the race will be added to establish the classification.
Should a participant fail to observe the regulations during practice or race, Race Control has the possibility to inflict penalties. Any such infringements may be excessive speed in the pit lane or non-respect of flag signals.
