Great Britain's athletes holds the greatest number of records at the Championships with a total of ten, followed by Russia (9), Germany (7), and Spain (4). Marita Koch and Heike Drechsler each hold multiple records, Koch having broken both the 400 metres record as an individual and as part of the East German relay team and Drechsler holding the records for both long jump and 200 m. World records have been set at the Championships: the French 4×100 metres relay team ran a world record 37.79 seconds at the 1990 Championships. Several athletics events no longer take place at the Championships and thus the events are deemed defunct, and their records unchallengeable.
