Dai Green, who lives in Trowbridge and trains at the University of Bath, is a medal contender in the 400m hurdles.

The 26 year old is competing in the 400m hurdles and 4x400m hurdles.

Gold is within his reach if he can overcome Puerto Rican Javier Culson the man who has beaten him three times this season.

If there is some motivation for Dai, it is that he knows he can beat him when it matters, having secured gold at the World Championships in Daegu last year.

The 400m hurdles take place at 20.45 this evening.
