All competitors must be a mimimum of 16 years and if under 18 years they must have their entry contersigned by a parent or guardian. This age limit is in place due to the circuits insurance with regards maximum engine capacity sizes for certain age groups and the age mix of competitors within a single race.
We can however permit under 16 year olds to practice, but their is a criteria they need to meet which is sorted on an individual case by case basis. If you are the parent or guardian of a rider aged 14 or 15 who would like to Practice at the Clay Pigeon Raceway, please get in touch with the series Co-Ordinator.
Open Practice/Warm up
Timed Qualification session(s)
Pre Final (s)
All riders will take part in at least One Practice/Warm Up session, One timed qualification session, One Heat, a Pre Final and a Final.
Best Lap time acheived during timed qualification will determine the grid poisition for the Heat, the race results from the Heat will determine the grid positions for the Pre-Final and the race results from the Pre-Final will determine the grid position for the Final.
The running/grid order will be split into groups after timed qualification based on best lap time acheived, the faster riders will go into group A and the rest into group B and if entries are over 48 riders then we will have a Group C and an additional group for every additional 20 riders.
Riders have the chance to progress up a group by being placed in first or second in their group Heat or Pre-Final.
Note: The split groups are simply a way of reducing the number of riders in any race and that the lap times/speed of riders in each race/group are simular which reduces the number of lapped riders and the associated issues this causes in the late stages of a race. But it should not be viewed as a seperate championship or race as it is simply one championship race split into two (or even three) halfs with the faster riders in group A and the remaining riders in Group B (or even B and C) the first placed rider in the B Final will be awarded the same points as if being the last placed finisher in the A Final, so its just a split race not a seperate championship final.
All championship rounds will be held at the Clay Pigeon Raceway, with all planned fixtures scheduled as Saturday race events. The format for the 2019 series championship will be a 8 round (Best 7 scores from 8 to count) championship season from March to November inclusive with a 3 round winter series from December to February inclusive.
