Medal hopeful Michael Jamieson put down a marker for Commonwealth Games competitors.
The former Glasgow School of sport pupil ensured qualification for Glasgow 2014 by winning the 200m breaststroke title at the British championships in Glasgow this week.
The 25-year-old swimmer secured the fastest time in the world this year by winning in two minutes 7.79 seconds.
That was just 0.36 seconds slower than his record time, his London 2012 race which still stands as the British record.
The world number one’s win at Tollcross international pool on Thursday was Jamieson’s fourth British 200m breaststroke title in just five years.
The Glasgow 2014 ambassador said: “I’m pretty happy with that swim, so it’s job done in terms of qualifying for the Commonwealths.
“With just over 100 days to go, I’m right where I want to be in terms of preparation.”
Jamieson did not fare as well in the 100m breaststroke final, finishing third behind Ross Murdoch and Adam Peaty with a time of 1:00.53.
The week before, Jamieson broke the qualification standard time for Team Scotland comfortably at the Scottish National Open Championships in Glasgow.
There, the Olympic silver medalist posted a time of 2:08.01 in 200m breaststroke.
