Great Britain 4x400m relay captain Martyn Rooney has said that he is proud of the team's performance.
"I'm very proud to be British and very proud to represent my country. To be captain was amazing," Rooney told BBC Sport.
"The group of people we had on this team really rose to the occasion. We all came here to do the job. I'm very proud of everyone in this quartet who ran amazingly well.
"For Great Britain as a whole it's an incredible time. Hopefully next year going into the Olympics. We can come back and get stronger."
