History Overdosed on Instagram: "The 100m final at London 2012 was one of the fastest races ever run. Usain Bolt stormed to victory, defending his Olympic title in a stunning 9.63 seconds - the second-fastest time in history, just shy of his own world record. Yohan Blake followed in 9.75s, the quickest silver-medal time ever recorded, while Justin Gatlin claimed bronze in 9.79s. Even Tyson Gay, finishing fourth, clocked a remarkable 9.80s."
