Daniel Wiffen struck for his third Irish Open Championships gold of the week in the 800m freestyle on the final day of competition at the Aurora Centre in Bangor.
The reigning Olympic champion in the event, Wiffen clocked Seven minutes 58.08 seconds. Nathan Wiffen filled the runner-up spot, with Sunday's Well's Liam Custer taking bronze.
"I had a lot of racing, and I did an extra event this time. To be honest, I'm pretty happy with the 1500 at the start of the week," said Wiffen after his 800m win.
"I'm looking forward to what I'm going to produce at the end of the summer now. I've basically got a kick up the ass to try and do something."
Wiffen had already said he might leave his California training base if he was not happy with the times he recorded this week, and he may well move to Ireland to train at the National Centre in Abbottstown before the European Championships in Paris in August.
"I'm just going to talk to a lot of different people. I'll talk to Andy Reid (high performance director) to see what his opinion is as to what I should do, and then basically go back to the drawing board, rewrite the season, and come away with gold medals (at the Europeans) in the summer. It’s time to refocus and on to the Europeans now, and I can't wait."
Claire Custer, Liam’s sister, who had already won the 800m freestyle title, finished second to visiting Lune Swimming Club’s Fleur Lewis in the 1500m freestyle.
After a tremendous battle between the two, Lewis overtook Custer in the last five metres in 16:54.69, with Custer a mere 0.27 of a second behind.
Ellen Walshe won her fifth title this week in the 200m individual medley, hunting down Ellie McCartney to win in 2:13.51.
Bangor’s Jacob Armon was the fastest qualifier out of the heats for the men's individual medley final over the same distance, but he was beaten in the final by Jack Cassin.
Cassin won in a new Irish record time of 2:01.00, breaking Brendan Hyland’s seven-year-old Irish best by 0.52 of a second.
In the 50m freestyle heats, Lisburn City’s Matthew Hamilton set a new Irish junior record to progress to the final as the fastest qualifier, and he took gold in 22.75 seconds in a blanket finish.
Danielle Hill topped the qualifiers for the women's race over the distance and duly won her second gold of the meet in 25.27 seconds.
