Sprint specialist Francesca Halsall of British Gas Loughborough ITC won the final of the 100m Freestyle tonight.
The European Champion was almost half a second up on the rest of the field at the halfway point before Amy Smith fought back in the final length. Halsall held onto the lead and took the title well within the qualification standard after touching in 53.57.
"It was an okay race," said Halsall. "I actually expected to go a little bit faster than that tonight but to get on the team and do a time that was such a small margin of my time from the worlds in the summer is great.
"I'm in such good form at the moment so if I can carry that through to the Olympic Games, hopefully I can swim a bit faster there and get another medal.
"I think I was a bit more relaxed tonight. I had a bit more fun with it all which is something I never usually get to do with the 100m Freestyle because it's my main focus. But tonight the pressure was off because I'd already qualified. I had to make top four to get on the relay team but other than that, there wasn't really any pressure so it was nice to be able to swim like that.
Smith also met the required time to win the silver medal in 54.01, a new personal best for the Loughborough University swimmer.
Rebecca Turner (City of Sheffield) was delighted with her third place and spot on the Olympic relay squad, finishing in 54.83.
Stacy Tadd was chasing a new personal best tonight to achieve the Olympic qualification standard in the final of the 200m Breastroke final.
The University of Bath swimmer swam with intent taking an early lead and holding on despite a desperate dash for the line from Derventio's Molly Renshaw.
Tadd took gold in a lifetime best of 2.26.63.
"It was a great race and I'm over the moon," said Tadd. "It hasn't quite sunk in just yet but I'm sure it will do later when I see my parents - they'll be dead chuffed.
"I'm absolutely thrilled with the time. I couldn't have hoped for much better really tonight. Obviously Molly came back really, really fast. I didn't notice but I knew she would do that so I just had to hang on in there."
Molly Renshaw narrowly missed the qualifying standard and finished in 2.26.81
Individual Medley specialist Hannah Miley took the bronze in 2.28.46.
