Caster Semenya ruled out taking medications to lower testosterone levels but insisted she will continue competing after she won the 800 metres at the Doha Diamond League meeting on Friday. It was her first race since losing her appeal over a controversial gender ruling in the Court of Arbitration for Sport.

Semenya, 28, was only added to the 800m start list in Doha on Thursday morning, a day after her appeal against a new rule regulating testosterone levels for women athletes was rejected by the CAS.

The South African, a two-time Olympic champion, timed 1min 54.98sec to defeat Burundi’s Francine Niyonsaba, who clocked 1min 57.75sec and Ajee Wilson of the United States in 1min 58.83sec.

Semenya’s victory was seen in some quarters as her last over 800m with new IAAF rules governing testosterone levels coming into operation on May 8. But the reigning Olympic gold medallist said she is in no mood to quit.

‘About human dignity, human pride’

After her win on Friday – in the same city where she hopes to feature in September’s world championships – Semenya said she was fighting a bigger battle beyond the track.

“This is all about inspiring the world. This is more than a game, more than sports. This is about human dignity, human pride. What you do if you’re inspiring the world.

“People fight me, I don’t fight them. I live life and I enjoy it.”

“In September, of course, my main goal is to defend my title! But I am a crazy athlete, who goes from one race to another (from 400m to 5,000m) and I will continue.

“It was an incredible race tonight, I worked hard. I felt great, I am very happy. I did what I came to do.

“1min 54sec is a very good time. Now I will go home and train hard to do better than 1.54.”

Aleck Skhosana, president of Athletics South Africa, told AFP in Johannesburg that Semenya’s performance had put her critics firmly in their place.

“We are excited that Caster has done what she is known for ... despite all the challenges that she is facing,” said Skhosana.

“We encourage her to stay focused and do what she does best – which is to run and conquer the world.”

Asked if she intended to take hormone-suppressing treatment, Semenya said: “Hell no. No way.

“I don’t know what will happen next. But no-one should tell me what to do, if people want to stop me from doing something that’s their problem, not mine.”

After setting a new meet record, she told the BBC: “Actions speak louder than words. When you’re a great champion you always deliver.

“With me, life has been simple. I’m just here to deliver for the people who love and support me. I’m enjoying each and every moment of my life maybe because I have the love I need from my people.”

Semenya had challenged the measures, introduced by the IAAF, that will force women with higher than normal male hormone levels – so-called “hyperandrogenic” athletes – to artificially lower the amount of testosterone in their bodies if they are to continue competing.

The rules will come into effect next Wednesday and will apply to athletes competing in races over distances of 400m to the mile.

Semenya had earlier hinted at possible retirement, tweeting: “Knowing when to walk away is wisdom. Being able to is courage. Walking away with your head held high is dignity.”

Elsewhere on Friday in the Qatari capital, Britain’s Dina Asher-Smith cruised to victory in the 200m.

The European champion won in a season-leading 22.26sec ahead of Jamile Samuel of the Netherlands and Nigerian sprinter Blessing Okagbare.

Kenya’s Elijah Manangoi won the men’s 1500m, holding off a late charge from training partner Timothy Cheruiyot to win in 3min 32.21sec.

Hellen Obiri also starred for Kenya with the world cross country champion powering home to win the women’s 3000m in 8min 25.60sec.
