Olympic Games 400m champion Shaunae Miller-Uibo believes the women’s 200m world record is more reachable than the 400m.
Miller-Uibo, who is the best 200m/400m sprinter, won the Rio 2016 Olympic games 400m title and the 200m at April’s Commonwealth Games.
She has personal best times of 21.88 in the 200m and 49.44 over the one-lap event.
Former American Florence Griffiths-Joyner ran 21.34 on 29 September 1988 for the 200m world record. She also had the second-best time of 21.56.
Dafne Schippers 21.63, Elaine Thompson, 21.66 and Allyson Felix, 21.69 are the fastest women now.
In the 400m, Marita Koch of Germany ran 47.60 back in 1985. Since then no other woman has broken 48 seconds.
The fastest on the list that is still running is Allyson Felix at 49.26, the 74th best time ever.
