Great Britain's rowers dominated the day four finals at the Rio Paralympics with three gold and one bronze medal - including success for teenager Lauren Rowles four years after watching London 2012 from her hospital bed.
Rachel Morris won arms-shoulders single sculls, claiming Paralympic gold in a second sport eight years after her cycling time-trial triumph in Beijing, and Tom Aggar took bronze in the corresponding men's event.
Rowles and Laurence Whiteley then triumphed in the double sculls and the mixed coxed four team of Pamela Relph, James Fox, Daniel Brown and Grace Clough, plus cox Oliver James, were victorious too.
Rowles was 13 when, in February 2012, she lost the use of her legs when she was diagnosed with transverse myelitis, a rare paralysing condition that developed overnight.
She spent 10 months in hospital and watched London 2012 from her hospital bed while vowing to compete at the Tokyo 2020 Paralympics.
She represented England in wheelchair athletics at the 2014 Commonwealth Games in Glasgow before switching to rowing.
The 18-year-old from Bromsgrove said: "If you'd have told me four years ago from when I was sitting in a hospital bed watching London 2012 that I'd be here now winning a Paralympic gold medal I'd have said, 'No chance'.
"This medal means absolutely everything to me. Everybody says it's blood, sweat and tears that goes into this, but we've only been training for 18 months, but we've put every last ounce into this and it's just what pays off from hard work."
Rowles received her A-Level results last month and will return from Rio to study law at Oxford Brookes University.
There was a reception planned in Rio for the British rowers on Sunday night, giving Rowles the opportunity to enjoy her success.
"This is training for freshers' week," she added.
"I'm just going to enjoy Rio, not thinking about uni yet, but I'm excited to start a new chapter in my life."
Rowles and Whiteley had been a partnership for just 18 months prior to Rio.
"I was two-and-a-half-years waiting for someone like Lauren to turn up and thinking it would be worth it in the end," Whiteley said.
"At times (I thought) walking away and finding someone else would be easier to do.
"After all that, to be Paralympic gold medallist I'd absolutely do that again in a heartbeat."
The 25-year-old from Northallerton was treated for bone cancer aged 14, as part of group of 14 young people with similar conditions. He was one of two to survive.
"It's difficult because I think I was quite ignorant of it at the time," he said.
"Looking back, ignorance was bliss. I wasn't quite fully appreciating the sort of cancer that I had, the survival rate."
Rowles and Whiteley were aware of Morris' result in the first final before embarking on their own gold medal bid.
For Morris, who won road time-trial gold in 2008 and road race bronze at London 2012, six weeks after being hit by a car in training, it was an unexpected success.
She had surgery in April on her left shoulder, which flared up again this week, and was described as "an absolute warrior" by Rowles.
Morris, who had her legs amputated after developing reflex sympathetic dystrophy which involves a malfunction of the nervous system and causes extreme pain and sensory issues, said: "It's just the most incredible thing ever. It's going to be one of those days where you have a cheesy grin fixed on your face.
"To get a gold in a second sport and after a pretty tough run-in has been amazing.
"It's been a tougher journey than I thought, but I've had incredible support.
"I can't tell you what I've gone through to get to this point.
"If anybody can make any difference to somebody else's life, that's a massively important thing.
"If that enables somebody else to do something - whether it's grassroots or elite - then that's really, really important. That's what medals are about.
"Yes, it's personal, but it's also about giving people a way of believing that they can achieve something."
Pamela Relph was the only member of the mixed coxed four boat to have also won gold at London 2012, but they had won three successive world titles.
"The pressure was just sky high coming into this," she said.
"It's such an amazing crew. I knew coming through 250 (to go) I was going to be a Paralympic champion again.
"It was amazing. What a great day for our sport."
