List of World Records in Athletics - Ratification

Ratification

The criteria which must be satisfied for ratification also apply to national or other restricted records and also to performances submitted as qualifying marks for eligibility to compete in major events such as the Olympic Games.

The criteria include:

• The dimensions of the track and equipment used must conform to standards. In road events, the course must be accurately measured, by a certified measurer.
• Except in road events (road running and race walking), the performance must be set in a single-sex race.
• All team members in a relay race must be of the same nationality.
• Pacemakers are allowed, provided they have not been lapped; lapped athletes must give way.
• Drug testing immediately after the performance is now required for ratification of a record. Existing records which predate this requirement are still extant. Athletes who pass the immediate test but are later found to have been on drugs have their performances invalidated.
• In running events up to 200 m in distance and in horizontal jump events, wind assistance is permitted only up to 2.0 m/s. In decathlon or heptathlon, average wind assistance of less than 2.0 m/s is required across all applicable disciplines; and maximum of 4.0 m/s in any one event.
• In running events up to 800 m in distance, photo finish fully automatic timing is required.
• There is no restriction on altitude; since the thinner atmosphere of higher altitude provides less air resistance, locations such as Mexico City and Sestriere have previously been the sites of records in the sprint and jump events. See effects of high altitude on humans. Records set at high altitude venues are often marked with an "A" though that does not disqualify it as a record. Under those circumstances, a "sea level" best is also tracked by statisticians. Long-distance races run at altitude, with less oxygen available to the athlete, have shown to be to the athlete's disadvantage. Remarkable distance races run at altitude are also noted with the A. Currently the only standing record set at altitude is Sergey Bubka's pole vault. Based on the circumstances of his records (discussed below), the altitude was not a major factor.
• In road events, the course is not required to be a circuit, but the overall decrease in elevation between the start and finish shall not exceed 1:1000, i.e. 1 m/km.
• In road events, the start and finish points of a course, measured along a theoretical straight line between them, shall not be further apart than 50% of the race distance.
