Specification for World Ranking Events in 2001

Specification for World Ranking Events in 2001

1. Which events are World Ranking Events?

1.1 The events which are selected to be for IOF Ranking purposes are chosen by Federations.

The allocation for 2001 has already been decided

From January 2002, all Federations will be able to stage up the three WREs per year

In addition, Norway, Sweden, Finland and Switzerland are allowed to stage a fourth WRE in 2002, this reducing to three WREs from 2003 onwards

Putting on one or more World Cup events does not prevent a Federation from hosting in addition its normal allocation of WREs

Regional Championships which rotate on an annual basis between two or more Federations (e.g. Nordic Championships) can be WREs without affecting the host Federation's normal allocation of WREs

Federations must follow the criteria below:-

WREs shall be Open events (i.e. runners from any Federation can compete) except where a Federation stages its full allocation of three WREs, where one of the three could be a Closed event (e.g. its National Championships)

Each WRE shall provide one men's race and one women's race; these are normally of classic length.

Where a multi-day event is selected, the WRE shall be chosen as one of the days (and not the chasing start day, if there is one)

A WRE should not normally be a mass start event; Relay races cannot count.

A WRE should preferably not be a Sprint event

Each WRE shall be controlled by an IOF Licensed controller.

WRE results must be available electronically immediately after the event so that rankings points can be calculated automatically. They shall be in an approved format.
Any deviations from these criteria must be approved by the Foot-O Committee (via the IOF Secretariat).

1.2 All World Cup individual races count towards the World Ranking lists. However only the Finals (i.e. not qualification races) count. Where there are A and B Finals (or even C Finals), each race is scored as a stand-alone race from the point of view of points calculations.

1.3 World Championship Sprint, Short and Classic (Long) races (both Finals and Qualification races) count towards the World rankings lists.

2. The formula to be used for ranking ...

2.1 ... takes into account (a) strength of field at each event and (b) differing spreads of times at different events and is given by:
       RP = (MP + SP x (MT- RT)/ST) x IP
where the number of ranked runners (see 2.3 below) is 20 or more.

2.2 There must be at least 4 ranked runners in order for the race to qualify for the World Ranking scheme.

2.3 A ranked runner is defined as one who has scored World Ranking points in the 12 months before the event and whose average points score is greater than or equal to 600 and who finishes within the winner's time plus 50%

2.4 Calculate the mean MP and the standard deviation SP of the average unweighted (i.e. for IP=1.00) ranking points of all ranked runners

2.5 Calculate the mean MT and the standard deviation ST of the times of all ranked runners.

2.6 Using RT, each runner's race time, finally calculate RP, the race points for each competitor at the event.

2.7
If the number of ranked runners n is small (n < 10), the formula in 2.1 must be replaced by the following:-
      RP = 2600 - RT x (2600 - MP)/MT

2.8 If the number of ranked runners is such that 10 < n < 20 each runner's points is given by a weighted average of the large events points (RP_L, as calculated by 2.1) and the small events points (RP_S, as calculated by 2.7) as follows:-
       RP = RP_L x (n - 10)/10 + RP_S x (20 - n)/10

2.9 IP is a factor which depends on the status of the event. It normally equals 1.00. For WOC individual race Finals, IP is raised to 1.05.

2.10 The best four results in a twelve month period shall give the overall score of each ranked runner.

2.11 There shall be separate lists for men and women based on performances in Open, or M/W21E races only.

2.12 At the end of each year, both groups of ranked runners (i.e. men and women separately) shall have the points of each runner re-based so that their average points have an overall mean of 1000 and standard deviation of 200.
