Why are the ancient Greek Olympic Games still remembered today?

Almost three thousand years ago, in a sunbaked valley in Greece called Olympia, people gathered to run, jump, and throw things very far. That's it. So why on earth do we still talk about it today? Plot twist: those dusty footraces turned out to be one of humanity's longest-running ideas.
The Games began around 776 BCE — that's the first date written down, though they may have run even earlier. They happened every four years, like clockwork, and they kept happening for nearly twelve centuries. Imagine a tradition so stubborn it outlasted whole empires. Most things don't last twelve years. These lasted twelve hundred.
