Age falsification

Two athletes subsequently lost their medals as a result of fraudulently misstating their age on official documents: Bahrain's 2006 steeplechase silver medallist Tareq Mubarak Taher and Morocco's Ahmed Baday (1998 5000 metres bronze). In addition to this, later analysis of Moses Kiptanui's age when having won the 1990 1500 m showed he was marginally overage (aged 19 years, 315 days) at the time of his victory, though this result has not been rescinded.^[3]

Title defences

Given the age limitations on the competition it is rare that athletes get the opportunity to defend previous individual titles. A total of 22 athletes have managed this feat, eight of them men and fourteen women.^[3] In addition to this Anita Weyermann won the 3000 m title after taking the 1500 m title two years earlier.

Doubles

A total of fifteen athletes have won two individual titles at the same championships (nine men, six women). The majority of these are sprint or long-distance combinations, although Andrew Howe (200 m and long jump), Margus Hunt (discus throw and shot put) and Morgan Lake (high jump and heptathlon) managed to win novel doubles.^[3] Many others achieved a double between an individual victory and being a member of a winning relay team.
