Gurbachan Singh Randhawa, one of the country's track and field legends, on Tuesday said he has resigned as the chairman of the Athletics Federation of India's selection committee owing to his "advancing age".

The 84-year-old, who won a gold medal at the 1962 Asian Games in decathlon and finished a creditable fifth in 110-metre hurdles event at the 1964 Olympics, said his advancing age is "making it difficult for me to give the job my 100 per cent".
