Lunice Johnston of Vuma Reputation Management said Pistorius won't be in training because "he is still in mourning," the Johannesburg, South Africa, newspaper The Citizen reported Wednesday.
When Pistorius might return to his training schedule was a private matter, she added.
Pistorius is free on about $113,000 bail after killing Reeva Steenkamp at his home on Feb. 14.
He has admitted the shooting but maintains he mistook Steenkamp for an intruder.
