Kvalifikācija

LCQ 8 minutes + 1 lap (only when allowed by race schedule time constraints)

The Pole position session will be run on a fastest lap basis. 

When allowed by race schedule time constraints: If the number of registered riders is higher than the number of allowed riders, the riders will be divided into two groups by their numbers in the registration list, 1 st – 3 rd – 5 th (even numbers) etc. in group A and 2 nd – 4 th – 6 th etc in group B (odd numbers). These two groups qualify separately and will equally fill up the starting field for the pole position. A maximum of 4 places in the starting grid will be reserved at the end of the grid to riders qualifying in the “last chance qualify” session (LCQ), as specified at riders briefing briefing. The LCQ will be a racing session based on the fastest lap, with a maximum duration of 8 minutes. The riders entering LCQ will be the Last riders of the A/B groups qualify sessions. 

Starts

The starting grid for the first moto will be according to the result of Pole Position or lucky draw, the following moto(s) will start with the grid determined by the result of the previous one. Starting positions cannot be changed between riders.

When instructed by the starter, all riders will line up with their AB in the correct order. The starter will show a “2” board (turn your engines on) and check all riders. At this point, riders on the starting grid have the chance (by raising the hand) to call a 2 minutes countdown if they need. If no rider calls the 2 minutes Countdown the starter will show a “1” board (ready to go) and will start the race from 0 to 5 seconds.

When “1” board is turned on, there is no more possibility to raise a hand and to interrupt the start. After 2 minutes countdown has been carried out, no more interruptions (by raising the hand) are allowed in second start. “2” board signal and “1” board signal might be substituted by equivalent signals (I.e. lights or flags).

The top 4 from pole position in each category will participate in the finals at each event. Riders positioned in pole position as 5th will receive points for position 5th position = 16 points, 6th 15 points and so on as per UIM rule 310.03. 

The Parallel Slalom will proceed by direct elimination in two rounds, one on each circuit. In case of an equality, a third round will determine the winner and the rider with the fastest qualification time will choose track. The rider with the best time will face the rider with the third best time. The rider with the second best time will face the rider with the fourth best time. The Starting position for the 3rd round will be decided by flipping a coin.
