The President arrived a few minutes late with little fanfare for the start of the 10km at 7am and ran a few kilometres before he was whisked away by his official convoy.
Race organisers said Ramaphosa had to cut his run short as he had other engagements to attend to.
The president has made time in his understandable hectic schedule and will line up alongside the strong field of some 30‚000 athletes‚ who will be pounding through the streets of the historic township.
The main race (42‚2km) started at 6am‚ followed by the 21‚1km at 6.30am while the casual runners resume at 7am.
Ethiopian Sintayehu Legese Yinesu of the Nedbank Running Club was the first runner to cross the finish line of the 25th edition of the race in an impressive time of 2:19:10‚ scooping the men’s title and the R250 000 prize money which comes with it.
But it was South African sweetheart Irvette Van Zyl‚ also of the Nedbank Running Club‚ who stole the show‚ winning the women’s 42.2km marathon for the second year running and setting a new course record of 2:33:43.
She too walked away a quarter of a million richer.
The runners pounded the streets of Soweto and ran past historic sites such as Vilakazi Street‚ which is houses the homes of Nobel Prize winners Nelson Mandela and Desmond Tutu.
