The B-sample of Comrades marathon winner Ludwick Mamabolo has tested positive, according to the SA Institute for Drug Free Sport (Saids).

Mamabolo, whose A-sample tested positive for methylhexaneamine after he won the 89km ultra-marathon in Durban last month, would face a hearing on a doping charge, Saids CEO Khalid Galant said in a statement on Friday.

“Now the process to constitute a hearing will proceed and a date will be set where Mamabolo will be afforded the opportunity to defend himself against the charge of doping,” Galant said. – Sapa
