What is fastest time over 100 meters for age groups?

As of my last update, the fastest recorded times for the 100 meters vary widely by age group. For example, Usain Bolt holds the overall world record for men at 9.58 seconds, while the fastest time for youth athletes (under 18) is around 10.13 seconds, set by Erriyon Knighton. In women's categories, Florence Griffith-Joyner's world record is 10.49 seconds. Age group records continue to evolve as new talent emerges.
