It was a glorious day when 105-year-old Hidekichi Miyazaki shocked the world by not only running a race but breaking a world record in the process.

The Japanese centenarian became Guinness World Records oldest competitive sprinter after running the 100-meter dash at the Kyoto Masters Athletic Autumn Competition. Miyazaki finished the run in a respectable 42.22 seconds but wasn't impressed by his performance, reports Huffington Post.

"Today my target was 35 seconds ... I shed tears of disappointment because I was not in good condition. I am not satisfied with today's time. But I am satisfied that I could cross finish line," he said after the race, according to Guinness. 

He's sometimes called "Golden Bolt" after Usain Bolt, currently the world's fastest man, for cheekily copying the Jamaican runner's trademark pose. 

What's more astonishing than his competitive spirit and physical agility is that he only began participating in track and field in his 90s. After retiring, Miyazaki spent his free time practicing calligraphy and playing chess. But after his friends started passing away, he says he needed a hobby he could do by himself, reports Huffington Post. 

So ever since then, the spritely centenarian has been training, running every day and even practicing the shot put. 

It seems to have done wonders for his health. "The doctors gave me a medical examination a couple of days ago and I'm fit as a fiddle," he told reporters. "I've never had any health problems. The doctors are amazed by me. I can definitely keep on running for another two or three years."

Amazing.
