Adam Peaty continued to defy expectations by winning his third European Championship gold in Glasgow.
The 23-year-old smashed the championship record on his way to retaining his European 50m breaststroke crown.
Great Britain’s other medal of the day came in Edinburgh where duo Ross Haslem and Grace Reid clinched silver in the 3m springboard mixed event.
Haslem, who was selected after Tom Daley took a short-term break from the sport, formed an impeccable partnership to deservedly finish second on the podium.
Another day of medal success means Great Britain are still second in the medal table with four more incredible days of action still to come.
Peaty breaks another record
Adam Peaty insists three gold medals will soon become four at the Glasgow European Championships.
Peaty blew away the field in the 50m breaststroke event, touching home in 26.09seconds – just 0.16seconds off his own world record time to top the podium.
And with the 100m and 4x100m mixed medley relay golds already safely in the cabinet – his attentions now turn to today's 4x100m mixed medley.
The bad news for his rivals is that Peaty is still improving – according to the man himself who won silver at the Commonwealth games in the 50m event behind South Africa’s Cameron van der Burgh.
“I tried to right my wrongs and it just proves that I can get near that world record now and maybe next year even touch it again," he said.
“The execution from me was a nine but the race was a ten out of ten. I missed a few strokes and that cost me something, but I think even if I got them I would not have got a new world record.
“But for next year at the World Championships it is looking strong. It is looking very good technique-wise and very good power-wise.
“I am going to stay neutral now. I am going to rest for the rest of the day, get ready for the morning and then put on a good show against Russia.”
Elsewhere, both Freya Anderson and Siobhan-Marie O’Connor narrowly missed out on medals.
The 17-year-old Anderson touched home in fourth in the women’s 100m freestyle won by Sweden’s Sarah Sjoestroem.
But Anderson could at least console herself with a new junior European record of 53.61 seconds.
"I'll work on my turns and my start in training, so hopefully then more medals will come," she said.
"Transitioning from junior to senior is difficult so hopefully I've inspired a few of the juniors to do the same."
O’Connor touched home in fourth in the women’s 200m individual medley that was won by Hungary’s Katinka Hosszu.
"It was disappointing, but I live and learn, so just one of those things,” said O’Connor.
"I can barely stand now. I have to get to training - I don't want to feel what I felt again, so next time I come racing I'm going to be ready. "
Ben Proud posted a new British and championship record in winning his 50m freestyle semi-final and will be itching for glory in today’s final, while James Guy qualified fifth-fastest for the 100m butterfly final.
Imogen Clark set a new British record of 30.04 seconds on her international debut to qualify for the 50m breaststroke final.
Haslem and Reid win third diving medal of championships
Ross Haslam proved a more than capable substitute for Tom Daley by claiming European silver on Wednesday in the synchronised 3m springboard mixed event.
The Sheffield diver, 20, teamed up with Grace Reid in the absence of Daley – who has taken the rest of this year off on paternity leave.
And the new duo – in only their second competition together – combined for a personal best score of 308.67 from five dives as gold went to the German pair of Lou Massenberg and Tina Punzel.
Haslam said: “It is a bit of pressure obviously (replacing him). Tom Daley is Tom Daley – whenever I tell anyone that I dive, they ask: ‘Oh, like Tom Daley?,” he said.
“But it has been great to be here, diving with someone who is Scottish in Grace in Scotland – it has been great to be a part of it as well.
To come here and do what we needed to do and get a medal makes me very happy – we are absolutely chuffed.”
Meanwhile, Lois Toulson narrowly missed out on defending her individual 10m platform title.
Duckworth’s decathlon dream
British decathlon athlete Tim Duckworth finished in an impressive fifth place with a total score of 8,160 points at his inaugural European Championships.
The 20-year-old was positioned second going into the final 1500m dash, but unfortunately couldn’t keep with the pace of eventual winner Arthur Abele.
Acclaim also goes to British duo Sophie McKinna and Dan Bramble who finished seventh in the shot put and long jump finals.
Elsewhere, there were a number of success stories as member of Great Britain’s squad advanced into athletics finals.
GB sprinters Adam Gemili and Nethaneel Mitchell-Blake qualified for the men’s 200m final.
Eilidh Doyle and Meghan Beesley moved into Friday's 400m hurdles final and Morgan Lake cleared 1.9m to book a place in the women's high jump final.
Lynsey Sharp, Adelle Tracey and Shelayna Oskan-Clarke are all through to the final of the women's 800m, and Matthew Hudson-Smith is in the men’s 400m final.
Glasgow weather stifles time trial trio
Two-time national champion Hayley Simmonds, who has struggled with injury this season, finished in eighth place in a time of 44:07 having hit every checkpoint inside the top ten.
"I was probably more cautious than I needed to be,” she said.
“I broke my elbow at the women's Tour de France seven-and-a-half weeks ago and had surgery.
“I did not want to risk coming down on it today, setting myself back, then basically being in the same position for the World Championships [in September] as I am now.
"I looked at the weather forecast, and it said dry, but I've learnt from my three days up here that you kind of ignore what it says and assume it is going to rain.”
Meanwhile, Alex Dowsett finished as the leading Brit in the men's event in 54:13.84 – 30 seconds behind eventual winner Victor Campenarts.
Yet for Doswett, a top-five finish was perhaps not something expected earlier in 2018.
"I've felt all this season there's been something wrong with my position on the bike. I've taken it back to the drawing board,” he said.
"I've come to the stark realisation this year that the reason I used to win a few more races than I do now is that I was ahead of the game and everyone has caught up. I need to get back ahead of the game.”
Fellow Brit Harry Tanfield finished 16th in 55:53.71.
Finally, in the inaugural Golf European Championships - newly crowned British Open winner Georgia Hall made positive steps with partner Laura Davies by beating Spain's Noemi Jimenez and Silvia Banon in the women's team competition.
