Cape Town - It would seem every South African set their alarm for 02:15 on Sunday morning, as Caster Semenya took to the blocks in the women's 800m final.
The early wake-up call was worth it as Semenya cruised to gold with a time of 1:55:28.
Semenya was favourite to win the women’s middle-distance race and ran a national record in the final.
It was an all-African podium as Burundi's Francine Niyonsaba took silver with a time of 1:56.49, while Kenya's Margaret Wambui in 1:56.89 took bronze.
This is the 25-year-old Semenya's second Olympic medal, after winning silver in the 800m at the 2012 London Games.
