Prime Minister Narendra Modi today wished luck to the Rio-bound Indian contingent and exuded confidence that they will not only clinch medals but also win hearts with their conduct during the Olympic Games starting on August 5.

Modi today flagged off 'Run for Rio' event at the Major Dhyan Chand National Stadium to cheer for the largest ever Indian contingent who will be participating at the multi-sport event in Rio.

Thousands of school children, wearing masks of Rio-bound Olympians, participated in the 'Run for Rio' from Major Dhyan Chand National Stadium to Jawaharlal Nehru Stadium.

"Wherever our athletes go, India is visible not only on the ground but in their conduct as well. I am confident that these players will win hearts with their behaviour during the Games. They will introduce the great Indian heritage to the world," he said.

"I want to convey this to the members of Indian contingent that there will be many athletes from all over the world but there are 125 crore Indians standing behind you. When we will hoist the tri-colour here on the occasion of 70th Independence Day, I am sure that our national flag will also be hoisted in Rio during this period," said Modi. He also urged the youth to work hard for 2020 Olympics and said the focus should be on sending more than 200-member contingent to Tokyo.
