These matches are held between two teams of eight riders who are numbered 1 to 8. The two riders with the lowest averages in each team are the reserves and must be programmed at Nos. 7 and 8 (in any order). In addition, the three riders with the highest averages in each team must be programmed at Nos. 1, 3 and 5 (in any order).
The heat format is determined as follows:

| 4: | 7 (B-A) | 8 (D-C) | 7 (C-D) | 8 (A-B) |
| 5: | 1 (C-D) | 2 (A-B) | 3 (B-A) | 4 (D-C) |

Riders take the starting gate positions indicated in parentheses. The actual gate sequence used during the match is determined by the team captain winning the toss of a coin prior to the start. Gate A is on the inside of the track, whilst Gate D is on the outside.
Each reserve may have a maximum of seven rides that can be taken at any time. All exclusions count as rides, and a reserve that has been excluded may not be used in the same heat again.
If both reserves in a team are declared injured, the rider with the next lowest average is eligible to ride in Heats 4 and 15.
All riders must take at least two rides prior to Heat 15 unless declared injured. If a rider is unable to take the minimum number of rides, their place in a heat may not be taken by any other rider until this requirement is met (i.e. a team may not track a rider). For the purposes of this regulation, an exclusion for a starting infringement or exceeding the two minute time allowance only counts as a ride if the excluded rider is not replaced.
In Heats 5 to 14, a team behind by six or more points may substitute a programmed rider with any other rider in the team, provided each rider is only used as a tactical substitute once. A substitute rider takes the helmet colour and starting gate position of the replaced rider. Both riders in a heat may be substituted in this manner, provided the Referee is clearly notified which substitute replaces which rider.
After Heat 15, each team nominates their riders for the three remaining heats; the home team declaring first. Riders Nos. 1 to 6 may only be nominated as follows: Heat 16 - two lowest scorers, Heat 17 - two middle scorers, Heat 18 - two highest scorers. The scores from programmed rides only are counted and bonus points are included. Team members scoring an equal number of points may be nominated for any heat where they are eligible.
The team scoring the greater number of points over all heats is declared the winner. When teams score an equal number of points, the match is declared a draw.
