James Wilby was given no time to relax after last night's silver medal in the 100m breaststroke - back in the pool this morning for the 200m heats.
The 24-year-old swam in the second heat of the 200m event just over 15 hours after the record breaking 100m event, and showed the European competition that he still had plenty to give.
He qualified just behind British Record holder Ross Murdoch, who finished in the fifth fastest time.
Murdoch said: "This morning was a good heats swim, I've learnt my lessons over the last few years.
"I don't know what it is about heat swims, but they always feel really good. When I stick to what my stroke rate is normally on the way out I always end up way too fast so I just had to take it really slow, build the back end and see what I can come away with - and I did come away with a good time.
"People have said to me 'You must have been gutted not to win at the Commonwealth Games' and I was disappointed with that swim, but not because of the result. It was to do with myself and the way I had executed my race plan so when I look back at the 100m race there was nothing wrong with that race plan - it was my fastest back end ever so at the end of the day I put myself in the best place possible, but it just turns out James is having an absolutely outstanding year.
"There have been quite a few times where I have been on the right side of the result from James' perspective. Times when I've beaten him by a couple of hundreds of a second, so it's about time he got some back!"
There was also a tough contest in the 200m Individual Medley where Mark Szaranek, Max Litchfield and Duncan Scott finished in the fastest three times.
Szaranek swam a personal best time to secure the fastest qualifying spot with Litchfield, at his first major meet since a shoulder injury, swam a Season's Best to clinch sencond place. Duncan Scott missed out as only the top two swimmers from each nation can progress.
Tom Dean, who won the title at junior level last month, swam the 9th fastest time across the heats, also fast enough to have made the semis.
Alys Thomas was fastest qualifier in the 200m butterfly - the event she won in the Commonwealth Games - with 17-year-old Emily Large securing a semi-final spot in 12th, one place ahead of teammate Charlotte Atkinson.
A strong swim from Luke Greenbank saw him progress as the fastest Brit in the 100m backstroke in 8th, alongside Brodie Williams who won his heat and was 14th fastest. Nick Pyle and Elliot Clogg finished 16th and 34th in a field of 52 swimmers.
Holly Hibbott swam 4th fastest in the 200m freestyle with 0.05 seconds separating the next place Brits Ellie Faulkner and Kat Greenslade, who picked up a bronze in the 4 x 200m mixed relay last night. In the end Faulkner progressed to the semis in 7th, with Greenslade in 8th.
Britain then rounded off the heats session on Day 3 with the second fastest time in the 4 x 200m with Stephen Milne, Cameron Kurle, Tom Dean and Calum Jarvis winning their heat in a close fought final leg with Italy.
