Nerves got the better of Savannah Marshall at London 2012.
The Hartlepool boxer came into those games as the defending world champion and a hot tip to medal for Team GB.
But a quarter-final defeat to Marina Volnova of Kazakhstan crushed her dreams while her teammate Nicola Adams stormed to the gold and into the heart of every British fan.
Fast forward four years and Marshall is in Brazil kicking off the women’s boxing at Rio 2016 today with her middleweight fight with Sweden’s Anna Laurell Nash.
Since London, Marshall has been unseated as world champion – she took bronze earlier this year – but is the reigning Commonwealth gold medallist.
But after a tough time of it with injuries, the 25-year-old insists she could not be in better shape ahead of her second Olympic campaign
"Preparation has been great,” she said.
"I don't think anything will ever top a home games, although if I win a gold then it will. I didn't perform in London so as long as I perform I will be happy. Nerves got the better of me then but I am much better now. "I am four years older and a lot more mature. Qualifying was so hard but that was the best part for me. It will be hard in Rio so I don't want an easy ride."
And while Adams may take the headlines – Marshall’s podium prospects are not to be underestimated.
But the girl herself quite enjoys living in the shadows.
"When we were in London it received a lot of attention but now it is just normal - which is great, it's what we want,” she added. "The whole team is inspirational, not just Nicola, so I'm just glad to be part of a team. She is great and I take a lot from her but I want to be my own person.” The men’s boxers have struggled in Rio but Rob McCracken, the man who guided Carl Froch to the world title, insists Marshall is ready to rumble.
“She’s timed it just right,” he said.
“Savannah has spent the last 12 months working really hard, she’s had injuries which have set her back a long way.
“But the last 12 to 15 months she has really got it together, probably starting at the 2015 European Games in Baku. “Savannah lost to the European Champion, but it was a close one, she’s really pushed on from there, shown great character to shake off a couple of knock-backs when she’s had close defeats.
“She’s never lost motivation at any point and deserved her place at the Olympics after winning bronze at the worlds.
“I believe she now deserves a place on the medal podium. We hope she can do that and she is certainly good enough.” Sportsbeat 2016
