Kevin Young ran 46.78 seconds when he took Olympic gold in Barcelona in 1992. Now Karsten Warholm is the fastest of all time when he ran 46.70 in front of a jubilant home crowd in Oslo.

After the race, the two giants talked to each other.

- It was you who set the bar so high.

You were ahead of your time and you were the one who set the level, Warholm told Young who responded with a demand for a six-pack of beer.

- I look forward to it.

You are a legend, Warholm continued.

Young paid tribute to the Norwegian who took the record from him.

- You're GOAT (Greatest Of All Time).

You are the only one with three times in 47 seconds.

The only one on the planet who has done that.
