She's 30 years old.
Shelly-Ann is 37 and Elaine is 32.
Richardson should be the favorite but even if she wins, it wouldn't be a flex because she never beat them in their prime. To put things into perspective Bolt was 30 in his final Olympics and he was past his prime. He ran his last race and finished 3rd at the age of 31.
SO all of them are past their prime. The Clayton sisters are next up. Richardson just got lucky. Jamaica's big 3 are all past their prime, and the next crop are too young.
Richardson would have break Flo Jo's record, in order to solidify her spot as an all time great.
