With most of the lights turned off in the Olympic Stadium, Usain Bolt celebrated his ninth Olympic gold medal by organising his own javelin competition.
After his news conference ended in the early hours of Saturday morning Brazil time, the Jamaican sprint superstar - who says the Rio Games are his last - came back onto the track surrounded by volunteers, and started throwing a javelin.
Usain Bolt just threw the javelin 56 meters while messing around with volunteers in a darkened Olympic Stadium. Really.— Tim Reynolds (@ByTimReynolds) August 20, 2016
Eddie Pells, national writer for the Associated Press witnessed the bizarre scene from the press tribune.
"From the darkened field below, the shouts of "Usain Bolt, Usain Bolt" started ringing out.
"I squinted, saw a tall man in yellow shirt and shorts hoisting a javelin, with a few dozen workers and cameramen surrounding him.
"The man took a few long steps, reared back and let the javelin fly. It pierced the grass, not all that far downfield, but a pretty nice throw nonetheless."
Bolt posed for some pictures afterward, the javelin - which he requested a formal measurement of - still stuck in the Olympic Stadium turf.
Bolt's final throw, by the way, would have earned him a sixth-place finish at this year's Jamaican national championships.
