Great Britain's Hannah Miley remains upbeat following her fifth-place finish in the women's 400m individual medley.
The Scot was adamant that she gave it her all in the final, noting that it was an improvement on her placing in the same event at Beijing 2008.
She told BBC Sport: "Apologies if anyone had high expectations of me, I gave it everything I had.
"It really was about who could recover the quickest from the morning. I'm gutted but I couldn't give it any more - but it's one place better than I got in Beijing."
China's Shiwen Ye took the gold medal in the event, setting a new world record time of 4:28.43 in the process.
Elizabeth Beisel of the USA secured silver with a finish time of 4:31.27, while Ye's compatriot Xuanxu Li bagged bronze.
