World Athletics Rankings

There are 46 outdoor men's and women's athletics events that are subject to IAAF World Rankings and categorised as "Main Events". For each sex, this covers nineteen track and field events (seven track running events, three obstacle track events, four jumping events, four throwing events, and a combined event), two road running events, and two racewalking events.

In addition, performances in other events classed as "Similar Events" may count towards an athlete's world ranking.

There are a total of ten competition categories, which affect the number of points given for a placing score. Competitions are assigned a competition category code based on the level of the competition. There are four special categories for the foremost global and continental competitions, followed by categories ranked from A to F for other competitions. Competitions must adhere to IAAF rules and have either an IAAF, area association or national association permit status to be eligible for scoring. Categories apply to the senior age category, unless otherwise stated.[3]

The scores assigned to an athlete based on a given performance are derived from the IAAF Scoring Tables of Athletics. Different scores are assigned for outdoor and indoor competition. For throws and hurdles, only performances using senior level throwing implements or hurdles will be considered for scoring.[9]

The effects of wind are considered for the result scores in the following events: 100 metres, 200 metres, 110 metres hurdles, 100 metres hurdles, long jump and triple jump. A lack of a wind speed reading (noted as NWI) in any of these events results in an automatic 30-point deduction from the performance score. A tailwind reading from +0.0 m/s to +2.0 m/s results in no point adjustment. Tailwind readings above +2.0 m/s result in a 0.6-point deduction for each 0.1 m/s of wind, for example +2.1 m/s will have a deduction of 12.6 points. Headwind readings over −0.0 m/s result in a 0.6-point addition for each 0.1 m/s of wind, for example a performance into a −1.0 m/s headwind will receive an additional 6 points. In triple jump and long jump competitions, the athlete's best non-wind-assisted jump may be taken as their best performance of a competition if this receives more points than a further, wind-assisted jump.[9] Special rules also apply to the combined events: if an athlete performance has +4.0 m/s wind assistance or more and the average wind reading in all events is over +2.0 m/s then a 24-point deduction applies. A lack of a wind reading results in an automatic 24-point deduction from the performance score.[12]

For road running events, result score deductions will apply if the overall net drop in elevation of the course exceeds one metre per kilometre of the race distance (e.g. a downhill of over 10 m for a 10K run). Where the net drop exceeds this ratio, then a deduction of 0.6 points will apply for each 0.1 m drop per kilometre, for example performances on a course with a net drop of 1.1 m per kilometre will be subject to a 6.6-point deduction from the result score.[11]

Placing scores vary based on the event, the competition category, and the placing of the athlete. Higher category competitions assign placing scores for a greater number of athletes, from the top 16 placings in the OW category down to only the top 3 athletes in the F category for track and field events. The number of points awarded for a placing ranges from a high of 350 points for winning a track and field event at Olympic or World Championships level down to 5 points for third place in a category F track and field competitions.[9]

Given the variability in course type and distance at the IAAF World Cross Country Championships, that competition awards placing scores only and no performance score is calculated. As a result, a much higher placing score is assigned to this competition.[9]

The performance score is the combined total of the placing score and result score of an athlete performance. Only one modification is made to this score, relevant to track and field events only: performances older than 9 months from the ranking date will have 20 points deducted, those older than 10 months will have 40 points deducted, and performances older than 11 months will have 60 points deducted.[9]

An athletes ranking score is the average of their best performance scores within the ranking period. The ranking period is 12 months for all field events and track events of 5000 m or less, and is 18 months for 10,000 m, road running, racewalking and combined events. The number of best performances considered for the ranking score varies by event, with five performances considered field events and track events of 1500 metres or less, three performances for the 3000 metres steeplechase, 5000 metres, 20 kilometres race walk and road running (half marathon or 10K run) rankings, and two performances for the 10,000 metres, decathlon, heptathlon, marathon and 50 kilometres race walk.[9][11][10][12]

In all events, athletes will receive additional points in their ranking score if they have broken or equalled a world record in their main event or a similar event, with 20 points for a new record in a main event, 10 points for equalling the record in a main event or a new record in a similar event, and 5 points for equalling a world record in a similar event.[9][11][10][12]

An overweighting rule is applied to performances at the Olympic Games or World Championships (OW), and Diamond League finals (DF). Only one such performance from those competition categories will be used to calculate an athlete's ranking score, even if the athlete has multiple such performances within the ranking period. In contrast, the most recent performance scores at an area senior outdoor championships remain eligible for the ranking calculation even if that performance falls outside of the ranking period.[9]

In order to receive a ranking score, athletes must have recorded a sufficient number of performances scores within the ranking period, and some of these performances scores must be a main event category.
