Michael Johnson says Bolt capable of running 400m in 42 sec

American track & field legend, Michael Johnson, believes Usain Bolt is capable of adding the 400-metre world record to his growing list of accomplishments.



Johnson, who is in the island for a BBC documentary with Bolt, believes the world record holder for the 100 and 200 metres is capable of running the 400 metres in 42 seconds.



However, he said Bolt will have to develop his strength and speed endurance.

On the matter of how much faster Bolt can run in the 100 and 200 metres, Johnson, the king of track in his time, said he doesn’t think anyone, even Usain knows.
