Usain Bolt and Justin Gatlin to do battle again in 200m

“I’m just trying to get through these rounds using as little energy as possible and then give it my best in the final.”

Usain Bolt and Justin Gatlin resumed battle as the 200 metres got under way at the World Championships.

Two days on from riding to the rescue of his beleaguered sport, the Jamaican began his bid to add half-lap glory to his 100 metres crown.
