Shaunae Miller-Uibo won her first professional race as a mother when she ran a season’s best 51.83 to win a 400m race at the Diamond League meeting in Zurich on Thursday. The 29-year-old two-time Olympic champion, who gave birth to her first child in April, ran in a non-Diamond League event for the first time this season, as she works her way back to competitive fitness.

She just managed to edge Annina Fahr of Switzerland who ran 51.97 for second place. Fahr’s compatriot Julia Niederberger finished third in 51.11.

Reflecting on the season so far, the Bahamian star stated, “It has been a long season, and obviously it would have come in handy for this to be the start of it - I just have to build for next season, and to get the body used to the shock again - and be ready for next season.

“Having become a mother has no comparison [to her greatest athletics achievement]. This is my greatest blessing, and I love that boy so much. I am going to go back into things, and I just want to make him proud. I want to get back up and, hopefully, whatever happens next year, I am doing it for him.”
