Rules

The 5 best results from the last 365 days are considered for the ranking.
There are 3 classes of races:

HIGH: Individual Belgian Champs are the most important races. They give 2.5% more points than MEDIUM races.
MEDIUM: All other national events, interland and regional events that are WRE.
LOW: regional events. They give 5% less points than MEDIUM races.

To be considered for the Belgian Ranking, a race must:

Be organized by ABSO-BVOS or one of its members.
Have at least 5 ranked runners completing the race (4 for the women class).
Be marked as BRE (Belgian Ranking Event)

These events will be marked as BRE :

All national events (MEDIUM class)
All individual national champs (HIGH class)
2 days from the Belgian 3 days (MEDIUM class)
All WOC-WC selection races (MEDIUM class)
Interland race (MEDIUM class)
9 regional events from VVO (with at least 2 sprints, 2 middles and 2 longs)
9 regional events from FRSO (with at least 2 sprints, 2 middles and 2 longs)

These categories are considered :

for National events, only the Elite classes are considered
for VVO regional events, the A class for men and C class for women
for FRSO regional events, the A class for men and B class for women
for FRSO events, only the Elite classes are considered

To be considered for the Belgian Ranking, a runner must:

Be a member of a Belgian Club
Have completed at least one ranking race in the elite class when available or in the H21-D21 class when not (for regional events only)

Points are computed according to IOF World Ranking Rules with these deviations :

If there are less than 15 ranked runners finishing the race, IP is reduced by 0.005 (was 0.01) for each runner missing.
For women class, IP is increased by 0.05.

To compute the points of the first race, these points have been used (points computed by applying the standard formula with MP=1000 and SP=200).
