Champion Jamaican sprinter Shelly-Ann Fraser-Pryce will hang up her spikes after next month's world championships in Tokyo having redefined what is possible for women in sport.

The three-time Olympic and 10-time world gold medalist announced she would compete for one more season in 2025, saying she had unfinished business after withdrawing from the 100 meters final at last year's Paris Olympics due to injury.

"I didn't get the opportunity to do what I know I could have done in that moment," 38-year-old Fraser-Pryce said on a video call with reporters.
