Neeraj Chopra's historic feat in winning India's first-ever track-and-field gold at the Olympics will be commemorated every year, officials said Tuesday, as the javelin star spoke of his desire to inspire future athletes.

A medal-starved India revelled in Chopra's stunning achievement in Tokyo, which ended a more than century-long wait for an athletics gold, with politicians, celebrities and the general public heaping praise on the 23-year-old.

The Athletics Federation of India said August 7 -- the date of Chopra's triumph -- would be dubbed "Javelin Throw Day", with annual state meets for the sport held across the nation of 1.3 billion people.
