British/National/Provincial League 13-heat Match

National League: 1961
Provincial League: 1963-1964
British League: 1965-1968
British League Division 2: 1968

These matches are held between two teams of seven riders who are numbered 1 to 7. The rider with the lowest average in each team is the reserve and must be programmed at No.7.

The heat format is determined as follows:

Heat   HOME TEAM     AWAY TEAM  
Red Blue White Y/B
1: 1 2 1 2
2: 3 4 3 4
3: 5 6 5 6
4: 2 7 2 7
5: 5 6 3 4
6: 3 4 1 2
7: 1 2 5 6
8: 4 7 4 7
9: 5 6 1 2
10: 3 4 5 6
11: 1 2 3 4
12: 3 6 1 5
13: 1 5 3 6

The team captain winning the toss of a coin prior to the start chooses the starting gate positions for the first heat (A & C or B & D). These gate positions then alternate every heat. Gate A is on the inside of the track, whilst Gate D is on the outside.

The reserves may have a maximum of five 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.

In Heats 5 to 13, 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.

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.
