A GOLD medal and a new personal best – not a bad evening’s work from Dartford sprint sensation Adam Gemili.

The Blackheath and Bromley athlete won Britain its first gold medal in the World Junior Championships as he ran 100m in a sensational 10.05 seconds last night (July 11).

This effort smashed his previous personal best of 10.08 seconds, which initially propelled him into the spotlight last month.

Not only is Adam’s time a new World Junior Championships record, it is also a new British junior record, beating the previous mark of 10.06 seconds set by Dwain Chambers 15 years ago.

Adam, who will next run for Team GB at London 2012, said after the race: “I just told myself to stay relaxed and stay focused.

“I’m not going to lie, I was nervous before the race - it’s a World Junior final, it’s in this stadium in Barcelona, how can you not be nervous?

“But you need to use your nerves in a good way - try to use them to help you run and I did it.”

The former Dartford Grammar School pupil won his semi-final earlier in the evening with a time of 10.18 seconds.

He added: “This is a massive stepping stone for the Olympics.

“If I had only made the final, it would have been a great achievement, to win makes it huge.”

When asked if a sub-10 time is on the cards at the Olympics, Adam replied: “I honestly don’t know.

“I’m feeling good and I’m running well, I just feel there is a whole lot more to come.”

Adam’s winning sprint was 0.12 seconds quicker than second place runner Aaron Ernest, from America.
