Lisa Mason quit the sport after finishing 23rd in the all-around competition at the 2000 Games.
But she's now back in competition, winning vault gold at the English Championships in Kent at the weekend.
Mason, who decided to return to the sport after watching Team GB gymnastics success at the London 2012 Olympics, will now set her sights on this month's British Championships, with qualification for April's European Championships the ultimate ambition.
Elsewhere, Max Whitlock, who won pommel horse and team bronze at last year's Olympics, won the English all-around title ahead of British team-mate Dan Purvis.
Two-time Olympian Hannah Whelan, 22, won the women's all-around.
