Adam Peaty remembers exactly where he was as South Africa's Cameron van der Burgh stormed to 100m breaststroke gold at London 2012.
"I was getting drunk in a field with friends," he recalls.
Just 17 and at a crossroads, he recalls seeing Craig Benson, a friend from junior days, make the 100m breaststroke. It was the wake-up call he desperately needed.
"100%, London 2012 inspired me the most I’ve ever been inspired," he said.
"I still use that opening ceremony for a little bit of inspiration now. It was just amazing; the show that we put on was the best on Earth really and for me as an outsider.
"I wish I somehow could experience what it would have been like to walk out to a home crowd with them all cheering."
Within a year, a newly-focused Peaty had made his first senior British team, at Rio he succeeded van der Burgh as Olympic champion, the South African taking silver, a title he retained in Tokyo.
"If you're watching now, and you're a kid, I was that same kid in 2012," he said after his Tokyo success.
"Just believe, follow your dreams and you can do what we do - and hopefully we'll see you on the team in eight years."
Tom Dean, the 200m Olympic champion in Tokyo, was just 12 when he and sister Connie were taken to watch the Olympic trials, having not secured tickets for the main event.
"Nine years after watching the 2012 trials, when I first started swimming, I never thought I'd be an Olympian, let alone win a medal. It all started that day," he said.
But Dean's favourite London 2012 memory wasn't in the pool but on the track - Greg Rutherford's long jump gold on that fabled night at the Olympic Stadium.
"When you hear that sort of thing, it's really special," said Rutherford.
"When you are an athlete you always hope that you're having a positive impact on other athletes, but you are rarely told. When he told me that in Tokyo, we both had a cry about it."
And it wasn't just Rutherford who inspired by Super Saturday heroics. Dina Asher-Smith remembers it clearly - she was carrying Jess Ennis-Hill's kit to the startline of the 800m.
As Team GB celebrated three golds in the space of 45 unforgettable minutes, Asher-Smith had a front row view of the action.
"I was 16, I wasn't making the team, so I thought I'd volunteer," she said.
“I was fortunate enough to be given that Saturday, which obviously I didn’t know was going to end up being Super Saturday.
"I remember being kind of disappointed that I wasn’t going to see Usain Bolt in the men’s 100m final but when I got there and witnessed probably one of the greatest nights in British athletics history I felt incredibly lucky."
Asher-Smith - the world 200m champion in 2019 - made her Olympic debut in Rio, winning 4x100m bronze, a medal she repeated in Tokyo despite battling with an injury.
Desirèe Henry was one of seven promising young athletes nominated by Team GB legends to lit the Olympic cauldron at Danny Boyle's masterpiece opening ceremony.
By Rio she joined Asher-Smith in the 4x100m relay team, one year later wining world silver at the same stadium were she lit the flame.
Joe Clarke was an inspiring member of the British junior canoeing team in 2012 - indeed his only stress for the Games for getting tickets.
But he took his place in the stands at Lee Valley White Water Centre as Tim Baillie and Etienne Scott won men's C-2 gold, pushed all the way by team-mates David Florence and Richard Hounslow.
"Being there, hearing that atmosphere, that was what I needed to spur me on, to really target Rio," he recalls.
"I remember thinking, 'I can do this too' and I put in such a training shift in that witner of 2012, by 2013 I was winning team selections."
