Griffith Joyner ran a stunning 10.49 seconds in the 100m quarterfinals at the U.S. Olympic Trials in Indianapolis, shattering the world record.
On July 16, 1988, at the U.S. Olympic Trials in Indianapolis, Indiana, Florence Griffith Joyner ran the women's 100 meters in a staggering 10.49 seconds during the quarterfinal round. The time obliterated the existing world record of 10.79 seconds held by Evelyn Ashford, representing an almost unprecedented improvement of three-tenths of a second in a single race—a margin rarely seen at the elite level of sprinting.
The performance immediately drew scrutiny regarding wind conditions, as anemometer readings at the time suggested the reading might not have been accurate; however, the mark was ultimately ratified by the IAAF (now World Athletics) as the official world record, a distinction it retains to this day, making it the longest-standing record in the event's history among ratified marks.
This achievement instantly transformed Griffith Joyner from a talented but underappreciated sprinter into a global phenomenon. Her combination of blistering speed, flamboyant one-legged running suits, and six-inch decorated fingernails captured public imagination worldwide, elevating women's track and field to new levels of visibility ahead of the Seoul Olympics later that year.
The 10.49 record stands as a testament to the extraordinary athletic peak she reached in 1988, and it remains unmatched by any sprinter since, a lasting symbol of her singular place in athletics history.
