Paralympic star Oscar Pistorius has returned to training. The South African got back to the running track on Friday, weeks before he is due to appear in court for the next hearing in his murder trial. Pictures released by his family show the double amputee training at the University of Pretoria. They say the “low key” training is to help him focus on finding the “right mental and emotional equilibrium” for the upcoming hearing and he is not preparing for a return to competition. Pistorius is charged with the pre-meditated murder of his girlfriend Reeva Steenkamp in February – Pistorius has said it was a tragic mistake.
