Sonnyboy Ngobeni, a 55-year-old man, has died after taking part in the Comrades marathon.
It is reported that the man travelled home with friends by car the day after the marathon.
According to Comrades Marathon spokesperson Delaine Cools, he was dropped off near his house.
“When Ngobeni failed to answer telephone calls on Tuesday morning, friends managed to eventually break into his house to find that he had passed away in his sleep,” she confirmed.
The Comrades Marathon Association stated that the man had been in good condition during and after the race.
The funeral will be held on Saturday in Mamaila Village, Limpopo.
