Ellie Simmonds won her third medal of the Games as she snatched a bronze in the S6 50m freestyle.
The 17-year-old admitted in the morning she was running purely on adrenalin and had found the heat 'a killer'.
However, on Tuesday night she returned to finish third in 36.11secs behind Mirjam de Koning-Peper and Victoria Arlen.

Simmonds was delighted and surprised by her bronze.
She told Channel 4: 'I'm so happy. I'm really chuffed to get a bronze medal, I can't believe it - I was only looking to get a PB.
'It's just going so well for me. I'm going to go back and prepare and look forward to racing my 100.'

Simmonds returned to her accommodation after the heats where she had a massage and physio as well as a two-hour sleep before returning to the Aquatics Centre rested.
She was taken aback by her performance, saying: 'A massive surprise really.
'This is my fourth best event and I was going in fourth so to come out with a bronze medal...
'I was actually going for a personal best but I think a bronze medal actually overtakes a personal best in the Paralympic Games.
'I am just so happy and to be on the medal podium again on my fourth event and it will definitely help for my 100.'
