Rio 2016: South Africa's Caster Semenya Wins 800m Gold
South African Caster Semenya had no problem in cruising to the gold medal in women's 800m event at Rio Olympics
- Semenya clocked 1min 55.28sec to win the gold medal
- Francine Niyonsaba of Burundi took silver in 1:56.49
- Kenya's Margaret Wambui claimed bronze in 1:56.89
South Africa's Caster Semenya cruised to victory in the women's 800m at the 2016 Rio Games on Saturday, producing a devastating final kick to claim her first Olympic gold.
The 25-year-old 2012 silver medallist turned on the gas with 150m to go to cross the line more than 1.20sec clear of the field in 1min 55.28sec.
Francine Niyonsaba of Burundi took silver in 1:56.49 with Kenya's Margaret Wambui claiming bronze in 1:56.89.
Semenya has been at the centre of a raging controversy in recent years because of her naturally occurring condition, hyperandrogenism, which causes elevated testosterone levels.
Rival runners have said they want authorities to revisit rules that limit the amount of testosterone allowed in competitors.
Semenya exploded onto the global athletics scene in 2009, winning gold at the World Championships in Berlin as an 18-year-old prodigy.
However her muscular appearance immediately raised suspicions, and a furore erupted when it emerged the teenager had been ordered to undergo a test to determine whether she was a woman.
Partially in response to complaints from rival runners and coaches that the condition gave her an unfair advantage, world athletics chiefs implemented restrictions on testosterone levels in 2011.
Following the introduction of those rules, Semenya's times slipped, with many assuming she was taking medication to control her testosterone production.
Even so, Semenya was still good enough to claim silver in the 2012 Olympics, only denied gold by a Russian runner, Mariya Savinova, who was later exposed as a drug cheat.
But a Court of Arbitration for Sport ruling last year judged the International Association of Athletics Federations restrictions illegal, freeing Semenya to compete in her natural state.
Since then Semenya has been head and shoulders above her rivals and is almost a full second quicker than anyone else this season.
On Saturday she never looked in trouble, biding her time after a 57.59sec opening lap.
Niyonsaba hit the front with around 300m to go but Semenya was always within striking distance.
With 150m left she made her move, calmly accelerating clear to take the lead as the race for silver and bronze unfolded behind her.
Canada's Melissa Bishop dug deep in the home stretch but was just pipped for bronze by Wambui.
