Last dance in Paris
The Olympics have seen the curtain fall on some stellar sporting careers
Shelly-Ann Fraser-Pryce
Also 37, the Jamaican sprinter had already announced that Paris would be a "last hurrah", saying that she wanted to "make different memories" after winning eight Olympic medals, three of them gold.
Fraser-Pryce won back-to-back 100m Olympic titles in Beijing 2008 and London 2012, and captured a 4x100m relay gold in Tokyo for good measure.
But, her Paris experience was a letdown. After coming through her 100m heat in 10.92, she was a no-show for the semifinal, reportedly injured in the warm-up.
"It is difficult for me to find the words to describe the depth of my disappointment," she said on her Instagram account.
"The support of my fans, my country, and the larger community has rooted me in immense gratitude that has sustained me throughout my career," she added.
