JOHANNESBURG - Olympic champion Caster Semenya has given a glimpse into her current state of mind.
She's taken to social media to comment on Wednesday's Court of Arbitration for Sports' verdict against her.
Her bid to challenge new rules on testosterone levels for female athletes was rejected.
Semenya's yet to reveal whether she'll officially appeal the matter.
On Thursday, she posted a message on Twitter, which may suggest she's thinking of walking away.
