Format
Gate positions In the Qualification Heats, riders are allocated starting gates. For the Semi-Finals, the group winners have first choice of gate positions (A&C or B&D). Gate A is on the inside of the track, whilst Gate D is on the outside. For the Final, the gate positions (A&C and B&D) are decided by the toss of a coin. Points scoring All heats are scored as follows: 1st = 4pts, 2nd = 3pts, 3rd = 2pts, 4th = 0pts This system is used to encourage team riding. A pair finishing first and second will score seven points, whereas a pair finishing first and last will score only four. Race points scored over all 'qualification heats' are used to determine the final group placings. Where two teams are tied for a place, the team who scored most points scored in the heat where they met go through. Where more than two teams are tied for a place, the tie is resolved as follows: most wins, most second places, ballot. ==Past winners==
