Keri-anne Payne smashed the British Record in the women's 1500m Freestyle taking eight seconds off the previous time. She then returned to the water for the semi final of the 200m Freestyle on the third day of the British Gas Swimming Championships.
Payne led from the gun and was two seconds up after 100m and built on that lead stroke by stroke.
She steadied her stroke and then continued to push ahead and with just 300m to go she held a seven second lead over the field.
The Olympic silver medallist won the gold with the new British Record time of 16:06.67.
"I kind of had the record in mind but didn't think I was going to go that far under it," Payne said.
"I was fine with lane one in the final. My coach said to go 17 minute for the final and I just did that. It was so nice that every single person on poolside was waving me on and supporting me
"I'm now looking for a good 800 and hopefully a PB to get qualification for the world qualifier.

Simmonds took silver in 1.01.16 and Loughborough University's Rachel Lefley just pipped Georgia Davies to the bronze after finishing in 1:02.02.
