This guide will help you select the correct seeding method and lane/order assignment methodThe seeding method example below is based on three (3) heats/groups with a total of 24 athletes (except for the specific indoor method). The lane/order assignment example is based on 8 lanes/athletes. 

For more details on seeding, please see this link.


Seeding method for heats/groups (this does not include lane assignment)

1) Alphabetical (BIB)

        Heat/group 1-3: Allocation according to BIB

2) Alphabetical (last name)

        Heat/group 1-3: Allocation according to the last name

3) Circle

        Heat/group 1: 1 - 4 - 7 - 10 - 13 - 16 - 19 - 22

        Heat/group 2: 2 - 5 - 8 - 11 - 14 - 17 - 20 - 23

        Heat/group 3: 3 - 6 - 9 - 12 - 15 - 18 - 21 - 24

4) Manual

        Heat/group 1-3: Manual allocation to heats/groups (drag and drop)

5) Random

        Heat/group 1-3: Random allocation to heats/groups

6) Timed / Results

        Heat/group 1: 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8

        Heat/group 2: 9 - 10 - 11 - 12 - 13 - 14 - 15 - 16

        Heat/group 3: 17 - 18 - 19 - 20 - 21 - 22 - 23 - 24

7) Timed oval (Indoor)

        Heat/group 1: 1 - 2 - 7 - 8 - 13 - 14

        Heat/group 2: 3 - 4 - 9 - 10 - 15 - 16

        Heat/group 3: 5 - 6 - 11 - 12 - 17 - 18

8) Zig-zag

        Heat/group 1: 1 - 6 - 7 - 12 - 13 - 18 - 19 - 24

        Heat/group 2: 2 - 5 - 8 - 11 - 14 - 17 - 20 - 23

        Heat/group 3: 3 - 4 - 9 - 10 - 15 - 16 - 21 - 22


After you have selected a heat/group seeding, you need to select a lane/order assignment method.


Lane assignment / Order assignment

1) Alphabetical (BIB)

        Lane/order 1-8: Allocation according to the BIB

2) Alphabetical (last name)

       Lane/order 1-8: Allocation according to the last name

3) Best-to-worst

       1st jumper/thrower: 1

       2nd jumper/thrower: 2

       3rd jumper/thrower: 3

       :

       8th jumper/thrower: 8

4) Half & half 

       Lane 1 and 2 and 7-8: 5-8 mixed randomly within lanes 1-2 and 7-8

       Lane 3-6: 1-4 mixed randomly within lanes 3 to 6

5) Half & pairs (IAAF standard) 

       Lane 1 and 2: 7-8 mixed randomly within lanes 1 and 2

       Lane 3-6: 1-4 mixed randomly within lanes 3 to 6

       Lane 7 and 8: 5-6 mixed randomly within lanes 7 and 8

6) Manual

       Lane/order 1-8: Manual allocation

7) Pairs 

       Lane 1 and 8: 7-8 mixed randomly within lanes 1 and 8

       Lane 2 and 7: 5-6 mixed randomly within lanes 2 and 7 

       Lane 3 and 6: 3-4 mixed randomly within lanes 3 and 6

       Lane 4 and 5: 1-2 mixed randomly within lanes 4 and 5 

8) Pairs oval (Indoor) - if less than four lanes, then the best pair always have the two outer lanes 

       Lane 1 and 2: 5-6 mixed randomly within lanes 1 and 2

       Lane 3 and 4: 3-4 mixed randomly within lanes 3 and 4

       Lane 5 and 6: 1-2 mixed randomly within lanes 5 and 6

9) Random

       Lane/order 1-8: Random allocation

10) Standard alley 

       Lane 1: 7

       Lane 2: 5

       Lane 3: 3

       Lane 4: 1

       Lane 5: 2

       Lane 6: 4

       Lane 7: 6

       Lane 8: 8

11) Waterfall (mostly for middle and long distances) 

       Closest to inside: 1

       Next closets: 2

       Next..: 3

       ...

12) Waterfall (reversed) (mostly for middle and long distances) 

       Closest to inside: 8

       Next closets: 7

       Next..: 3

       ...

13) Worst-to-best

       1st jumper/thrower: 8

       2nd jumper/thrower: 7

       3rd jumper/thrower: 6

       :

       8th jumper/thrower: 1



If you select the qualifying result as the basis for the seeding (i.e., seeding the final based on semi-finals), then keep in mind that athletes are ranked based on the following rules: 


1) Fastest heat winner (Q)

2) 2nd fastest heat winner (Q)

3) 3rd fastest heat winner, etc. (Q)

4) Fastest 2nd place (Q)

5) 2nd fastest 2nd place (Q)

6) 3rd fastest 2nd place, etc. (Q)

(Concluding with)

x) Fastest time qualifier (q)

x+1) 2nd fastest time qualifier (q)

x+2) 3rd fastest time qualifier, etc (q)
