She was the 2021 World Under-20 Championship bronze medallist in the 200 m. Ofili is the African indoor record holder in the event and holds Nigerian record (also at U20 level) over the distance with a time of 21.96 seconds, making her the first Nigerian woman in history (and second African woman) to break the 22-second barrier.

[5] Favour Ofili was named the female athlete of the meet at the 2019 African Under-18 Championships after winning the 200 and 400 metres with new personal bests in both.

Ofili bettered this mark at the African Games a month later, finishing second with 51.68 s and qualifying for the World Athletics Championships in Doha.

[1] She also anchored the Nigerian team (Kemi Francis, Patience George and Blessing Oladoye) to a gold medal in the women's 4 x 400 m relay at the Games.

As the youngest athlete at the World Championships in September, she improved her 400 m personal best to 51.51 s but was eliminated in the semi-finals.

She was able to find some comfort at the World U20 Championships a few weeks later in Nairobi, where she won bronze in the 200 m and two medals for relays, with her mark in her individual event being the third-fastest ever by a U20 woman.
