Team GB's Shanaze Reade has pointed to her poor start as the main reason that she didn't medal in the women's BMX final.
"I just didn't get the start I needed to win the race and that was it," she said.
"Today's schedule has been pretty hard. I just tried to stay focused and do my best and today it just wasn't good enough.
"At the moment, I'm pretty emotionless. I'm sure it'll sink in. I can't thank all these people enough for supporting me and I don't really know what to say."
