(CNN) -- South African "Blade runner" Oscar Pistorius has apologized for the timing of his complaints about the length of his rivals' prosthetic limbs after his shock loss in the 200-meter sprint at the Paralympic Games in London. Minutes after losing the race to 20-year-old Brazilian runner Alan Fonteles Cardaso Oliveira on Sunday, Pistorius accused the gold medalist and others in the race of wearing "unbelievably long" blades. "You can't compete on stride length. You saw how far (Alan) came back so, you know what, we're not racing a fair race here, but I gave my best on a great night," he said.
