Great Britain sprinter CJ Ujah has insisted that he is only focused on his own race after qualifying for the semi-finals of the 100m at the World Athletics Championships in Beijing.

The 21-year-old made it through the heats as he recorded a time of 10.05s, finishing just behind USA's Trayvon Bromell in his race.

Ujah refused to be drawn on talk over the battle between Justin Gatlin and Usain Bolt for the gold medal as he is concentrating on his own job.

"I am in the race myself," Ujah told reporters. "I don't want to talk about other people reigning supreme, I am going to compete to the best of my ability."

Ujah will race in the semi-finals later today.
