WATCH: PRICELESS! Usain Bolt`s reaction to Wayde van Niekerk`s WR 43.03 in 400m final

New Delhi: Usain Bolt is no stranger to breaking records.

The Jamaican did not shatter his own record on Sunday but beat Justin Gatlin to win the men's 100m final.

Prior to that, South Africa's Wayde van Niekerk put in a stupendous effort to shock the world in the 400m final.

He crushed American Michael Johnson's long standing record with a time of 43.03 seconds.

Wayde's performance was so spectacular, it even produced a big reaction from the great Usain Bolt.
