Caster Semenya 28, the Olympic 800m champion, 28, last month lost her challenge to the Court of Arbitration for Sport (CAS) against the implementation of a restriction on testosterone levels in female runners; a Swiss court temporarily suspended a new IAAF ruling mean while caster will not need to take testosterone-reducing medication to compete after.

“I hope following my appeal I will once again be able to run free,” she said.

“I am thankful to the Swiss judges for this decision.”
