Usain Bolt, the world’s fastest man, signed copies of his recently released autobiography, Faster Than Lightening. I’m not sure how much more we can learn about one of the most popular athletes in world, but hopefully it gives some personal insights into what everyone wants to know: how did he become so fast?

Many folks think this past summer’s World Championships in Moscow was Bolt’s swan song, as he captured three gold medals, cementing himself — if he’s clean — as the greatest sprinter of his generation. But according to reports, Bolt is focused on three-peating in Rio during the 2016 Olympics:

“I want to dominate the sport,” he declares. “To do it at three Olympics would make people think, ‘Wow.’ I am trying to separate myself from just being a normal track athlete to being the greatest athlete in history.”

Only time will tell if Bolt can capture the gold in Rio, but if his commitment to hard work is any indication, we’ll all be witnesses to history come 2016.
