Double Olympic champion, Caster Semenya, says no human being can stop her from running.

She was speaking after winning the 800-metres at the Doha Diamond League race in Qatar amid speculation over her future. It comes just days after 28-year-old Semenya lost a landmark case against the athletics’ governing body.

She challenged the International Association of Athletics Federations’ (IAAF) rules designed to limit testosterone levels in female runners but the Court of Arbitration for Sport (CAS) dismissed her appeal.

Semenya has 30 days in which to appeal the ruling to the Swiss Tribunal Court.

Friday night’s victory is her 30th consecutive win of an 800-metre race.
