Singh, 101 is widely accepted as the world’s oldest marathon runner but what is perhaps more amazing is that he didn’t take up the sport until he was 89 when he completed his first London marathon.

Singh has said that age has played a factor in his decision to quit marathons but it won’t stop him staying active, saying that he plans to run for “at least four hours a day” after his retirement.

“The reason for my good health is that I exercise daily and follow a proper diet regime.

“Nowadays, people are more interested in going to a gym, but I feel if they exercise regularly on their own they can be physically and mentally strong.” said Singh.

The Turbaned Tornado has completed marathons in New York, Toronto, Scotland as well as five London marathons, an honour for which he was made part of the Olympic torch ceremony in 2012.
