The 100 Metres Trivia Questions

IAAF rules state any tailwind above 2.0 m/s makes a time ineligible for records. This ensures fairness, as wind can significantly boost speed.

Since 2010, any false start results in immediate disqualification. The old rule allowing one warning was changed to speed up races and reduce gamesmanship.

The first 10m is critical for acceleration, but races are often decided in the latter 40-60m. Many sprinters lose because they decelerate less than rivals in the final phase.

As of 2024, around 190 men have broken 10 seconds. The statement is actually true! It's a counterintuitive fact—many assume it's still rare, but it's become routine at elite levels.

Florence Griffith-Joyner's 10.49 from 1988 beats Jim Hines' 9.95 from 1968. Women's times have improved dramatically, surpassing older men's marks.

While mostly anaerobic, sprinters do use some aerobic energy. The race lasts about 10 seconds, and aerobic contribution is minimal but not zero, especially in the final meters.

Since 2000, the women's record has been broken 5 times (by Jones, Jeter, Fraser-Pryce, Thompson-Herah) while the men's record has only been broken twice (by Gatlin and Bolt).

Bolt's 2009 record was set under older rules allowing a 0.100-second reaction time. Current rules set a 0.100 minimum, and his reaction was 0.146—still legal, but the record stands under previous rules.
