- Caster Semenya lost her case against athletics' world governing body, the IAAF
- She must now take pills to lower her testosterone level if she is to compete at distances between 400metres and a mile
- Semenya has confirmed she will run the 800m at the IAAF's Diamond League opener in Doha on Friday
- That will be her final race before the commencement of the IAAF's controversial regulations over testosterone levels next Wednesday
Fans have whispered words of encouragement to South African athlete Caster Semenya not to quit sports over what she terms as harassment.
Semenya lost a landmark case against the IAAF, this week and must now take pills to lower her testosterone level if she is to compete at distances between 400metres and a mile.
Semenya has confirmed she will run the 800m at the IAAF's Diamond League opener in Doha on Friday, in what will be her final race before the commencement of the IAAF's controversial regulations over testosterone levels next Wednesday.
But she heightened doubt about her future by signing off a tweet on Thursday with words that translate into 'I'm finished'.
Figures in the sport believe it is more likely the double Olympic champion will convert to the 5,000m rather than quit or bow to the requirement of taking medication to lower her testosterone in order to run the 800m or 1500m.
A further tweet from Semenya, who is also considering an appeal, read: 'Knowing when to walk away is wisdom. Being able to is courage. Walking away with your head held high is dignity.'
IAAF president Lord Coe has broken his silence on the subject, albeit briefly. Speaking in Doha on Thursday, he said: 'It is very straightforward for any association in sport. Athletics has two classifications — it has age and it has gender. We are fiercely protective of both. We are really grateful that CAS has upheld that principle.'
