Eleanor Simmonds impressed on the first day of the British Gas Swimming Championships in the 400m freestyle Multi Classification final, winning with 1005 points to take the gold in 5.27.09.
Simmonds, the multiple international gold medallist, is looking to book her slot on the ParalympicsGB team later in the year.
"I'm really happy with the gold medal," said Simmonds. "The swim was really good although it wasn't as good as I wanted it to be, I am happy with it.
"It was the first time racing in this pool, which is great practice. I've got the qualification time now as well so hopefully I'll be going to the Paralympics.
I knew I could hit the qualification time quite easily but you always have that bit of pressure and worry in the back of your head. You never know what is going to happen."
Hannah Russell, the British Record holder for the S12 category, took silver in a new personal best time of 4.46.76 with 905 points.
In third place was Heather Frederiksen with a score of 849 and time of 5.01.69.
Jessica-Jane Applegate stated her Paralympic intentions to the selectors tonight, posting a new personal best to win the 200m Multi Classification final at the British Gas Swimming Championships.
Applegate (S14) posted a time of 2.14.71 to win with a points tally of 996 to take first place and the gold medal.
"I feel like a champion right now," said Applegate. "It's great. I wanted to go out strong. I felt a bit like jelly on the blocks but I knew I had to do it now. This was the chance to impress and I did.
"Since I joined Norwich, they've really helped me improve.
"It was a bit scary having Natalie Massey in the lane next to me because I know she's gone faster than me but I told myself I had to take this chance."
Natalie Massey (S14), who trains at the High Performance Centre in Manchester, was also in fine form to finish in second place, with a points tally of 960 and a time of 2.16.38.
Chloe Davies (S14) was third in 2.17.86 and 929 points, a new personal best to put her in the mix for medals.
