Caster Semanya smashed the national record in her bid to winning the 1500-metre Diamond League season-opening race after posting a time of three minutes and 59.92 seconds in Doha, Qatar.
The South African is one of the athletes that could be affected by new rules from the International Association of Athletics Federations (IAAF) regarding hyperandrogenism, which impacts female competitors with higher than normal levels of testosterone who partake in track events that range from 400 metres to a mile.
The two-time Olympic gold medalist can be among those able to compete as long her levels are reduced to less than five nanomoles per litre (nmol/L) for an uninterrupted time of six months.
She said: ‘’I wanted to go faster, but had to slow down a little. It’s always been a dream to set the record and continue to push beyond my personal best.’’
‘’I think we definitely achieved what we came here for. I want to maintain this momentum throughout the season, but will also make sure I continue to keep healthy.’’
