Some of them had journeyed for hours to witness a nerve-jangling, heart-thumping 20-second thrill; a thrill like nothing else in the world.
Others had travelled much further, from Kingston, Jamaica, to the centre of the Olympic world for further proof of Usain Bolt's greatness.
This was exhilaration through acceleration. Bolt promised, delivered and started a party that would reverberate all through London's thriving West Indian population and out into the wider world. He grabbed a camera, took photos of his teammate Yohan Blake and struck his lightning pose.
This was another triumph for the Caribbean island, delivered by its speedsters. Bolt was fastest in 19.32sec, his best gallop across the 200m distance this season. Blake was second in 19.44sec, and another man wearing a JAM vest, Warren Weir, hit the line third in 19.84sec.
Bolt's own world record of 19.19sec, set in Berlin three years ago, remained intact.
But if you needed to be reminded this was a win for Jamaica-Jamaica-Jamaica, you only had to witness the celebrations outside the stadium, as the 80,000 spectators started their shuffle into the Olympic Park. All that was missing was a reggae soundtrack; a tune from that other Jamaican legend, Bob Marley.
One particular fan was on the brink of having a fit. Decked out in her green, gold and black outfit, a Jamaican-flag hat only just hanging on, she was suffering through a screaming, flag-waving hysteria.
"Oh my God. Oh my God," she screamed. "Usain Bolt. Oh my God."
Or was it, Usain Bolt is my God?
In the eyes of some, he is already a deity after becoming the first man to successfully defend Olympic 100m and 200m titles.
And what a place to do it. Jamaican culture twists through the fabric of London.
Bolt won the 100m final at these Games on the eve of the 50th anniversary of Jamaica's independence from British rule. Independence Day has already become independence week and it could stretch into months. Bolt, Blake and Weir. Three men in it together. One love, indeed.
