Fauja Singh is running ahead of his age. At the grand age of 100, Fauja Singh is the world's oldest marathon runner, reports dailymail.
Fauja Singh has already taken part and completed seven marathons since he turned 89. And he celebrates his centenary by become the first person to sign up to the 2012 Edinburgh race.
You must be be wondering what's his secret. Well, the key to conquering his daily 10-mile training regime is eating plenty of ginger curry and drinking copious amounts of tea.
If not learned by books he certainly has wisdom to share, 'The secret is being happy, doing charity work, staying healthy and being positive,' he said.
Fauja Singh developed his love for running whilst working as a farmer in the Punjab. But it was not until he moved to the UK, half a century later, that he took up the sport seriously.
With the help of his coach, Harminder Singh, he started challenging other pensioners to races and has now run five marathons in London, one in Toronto and one in New York.
Mr Singh, a Sikh, holds the world record for the men's over-90 category after completing the 2003 Toronto marathon in five hours and 40 minutes.
He is indeed 100 years old and still as fit as a fiddle and Fauja Singh is certainly showing no signs of slowing down.
