Great Britain completed the full set of medals on the final day of competition to cap a superb ICF Junior and U23 Wildwater Canoeing World Championships.
Having become U23 C2 classic world champions on Wednesday, Emma and Kerry Christie added silver in the sprint event on Saturday morning.
Kerry then capped a week beyond her wildest dreams when she claimed an incredible fifth medal in winning bronze alongside Lucy Guest and Laura Milne in the U23 women's K1 team final.
It took GB's medal tally in four hectic days of competition in the Czech Republic to six after three golds and a bronze in the classic programme.
“The C2 sprint medal was a complete surprise,” said team coach and proud dad Jamie Christie.
“They obviously had a chance because of the nature of the course, and they got it together and were so close to the gold. It was really nice.”
Jamie was full of praise for his team as well as their Czech hosts who stepped in to stage the competition last year after China had to pull out.
“It's been an absolutely amazing week,” he added.
“The Czech organisation has been just brilliant and there has been a really good atmosphere.
“I would say it's probably been one of the best events.”
Jamie believes it marks the most successful British wildwater team performance since the senior World Championships in 2010.
“All of them have been really amazing,” he added.
“There's been a positive team atmosphere and everyone has worked really well together.
“We've taken part in every team event and no-one has been afraid of having a go in a boat they haven't used before.
“Our style this week has just been to have as much fun as possible, sensibly, and if we make it fun, the results will come.
“The three junior girls we brought – Ciara, Elsie and Iona – have been amazing. The aim is to give them a really fun time to inspire them to come back for more.
“It's what we did with Kerry, Emma and Lucy (Guest) four years ago in Banja Luka, and look what it has led to.”
The Christie sisters were fourth quickest after the U23 women's C2 sprint heats, but they powered through the final with a much improved run.
It saw them shave almost three seconds off their previous time to go comfortably clear at the top of the leaderboard with 1min 10.85secs with three to go.
Swiss pair Hannah Mueller and Mona Clavadetscher, whom the Christies had beaten to gold in the classic final, returned the favour to pip the Brits by just 0.47secs.
But the final two pairs were unable to overhaul the sisters who took their second medal together.
A day before her 21st birthday, Lucy Guest stepped in as a late substitute for the U23 women's K1 team final and it earned her a second bronze after the classic U23 K1 on the opening day.
They topped the timesheets with two teams to go after posting a competitive 1min 11.88secs, eclipsing the Italian time by just 0.28secs.
Penultimate runners Germany then took top spot before the Czech team snatched a dramatic gold in 1:05.45.
Britain had interest in four of the morning's sprint finals at Roudnice Nad Labem before the championships culminated in the team sprint finals.
A self-confessed classic specialist, triple world champion Kerry was just happy to have qualified for the U23 women's K1 final.
Setting off second of the 15 finalists, a smooth run knocked almost two seconds off her heat two time in posting 1min 04.21secs.
After seven of the 15 finalists down, the 20-year-old paddler was in third, but ultimately settled for 10th place, 2.27secs outside of the medal positions.
Slovenian athlete Ana Steblaj proved a cut above the rest, clocking 1:00.18 to take the gold.
Competing in his first world championships, Huw Singleton was honoured to line up in a high-calibre junior men's K1 final.
The first to tackle the highly technical sprint course, the Nottingham Kayak Club paddler was the only Briton to break the one-minute mark in Friday's heats and did so again.
Huw finished a shade outside his qualifying time with 59.53secs. It left him less than a half-second outside the top 10 and three seconds adrift of a medal.
The spoils went to Matyas Novak (54.67) as the Czechs continued to dominate the medals on their home course.
Britain had two finalists in the junior women's C1, as classic C1 team gold medalist Molly Sandercock (16) lined up with teammate Laura Milne.
Laura shaved six seconds off her second heat time to post 1min 23.65secs for 10th position, while Molly ran into trouble navigating the canoe through the course and wasn't able to finish.
Marie Nemcova (1:07.41) gave the hosts another gold as French paddler Laura Fontaine was pipped at the post.
In the opening team final – the junior men's K1 – Huw Singleton found trouble at the top section and lost touch with team-mates Leon Tomlinson and Scott Ritchie.
He fought hard to recover and stopped the clock in 1min 11.03secs, a time still good enough for a top-three spot after seven finishers, despite the setback, and ultimately earned seventh place as the Slovenian team grabbed the gold from Italy.
Development paddlers Iona Patrick, Elsie Landsborough and Ciara Maloney ended their competition in the junior women's K1 team final.
Looking for experience as a bridge to future results, the girls came through the course smoothly until Iona unfortunately capsized just before the run to the finish.
Brothers Will and Sam Stevely, both juniors, teamed up with Elliott Massey in the U23 men's K1 team final.
After negotiating the course safely, the trio clocked 1min 08.29secs which left them in the bronze medal position after half of the 14 teams had gone before settling for a fine eighth place finish.
A capsize cost the British trio of Sam Stevely, Toby Wilde and Ryan Mallon a finish time in the junior men's C1 team final.
Less than half-an-hour after winning bronze in the K1 team final, Kerry and Laura raced back to the start and swapped boats for her ninth run of the championships – the U23 women's C1 team final.
Laura had the task of taking the trio home, but was caught out by a stopper in the final section and overturned, ending the team's hopes of recording a time.
A technical issue at the top of the course prevented the team of Elliott Massey, Regan Toop and Scott Ritchie from setting a time in the U23 men's C1 team final.
A busy afternoon and championships drew to a close with the U23 men's C2 team final where the combinations of Ryan Mallon/Toby Wilde, Huw Singleton/Leon Tomlinson, and Toby Peyton-Jones/Stevely went for Britain.
In a chaotic race, Britain was the only team to post a time with only three runners to go, and that despite a capsize of the lead boat approaching the finish.
They recovered well to get back in the boat and clock 1min 58.60secs, giving themselves a chance of a medal.
But they had to settle for fourth place with the Czechs coming through once again to take another world title.
