Double Olympic champion Caster Semenya has made a winning return to the track.
The South African, who cannot currently compete at distances from 400m to one mile due to World Athletics regulations, won a 300m race in Johannesburg in 36.78 seconds.
Semenya was taking part in the "Classic Shootout", a meet which features South Africa's top athletes racing alongside high school students.
The meet aims to get high school students to take up athletics and sport for enjoyment and competition.
Other stars involved included Akani Simbine, the Rio 2016 100m finalist, who beat Clarence Munyai in the men's 150 metres.
"I am here to stay. Track and field, you will still see my face," said Semenya. "That is all I can say for now."
Semenya, as well as the other two Rio medallists in the women's 800m, Francine Niyonsaba and Margaret Nyairera Wambui, are affected by World Athletics' Differences of Sexual Development regulations.
The 29-year-old is unbeaten in 31 straight races over that distance.
However, the rules do not cover distances under 400 metres or over one mile, meaning she was free to run in this 300m race.
She is currently appealing the regulations (and the Court of Arbitration of Sport's decision to uphold them) to the Swiss Federal Supreme Court.
In the meantime, she has signed to play football with JVW FC, a club owned by former South Africa captain Janine van Wyk.
