OLYMPIC cycling champion Anna Meares has been there and done that.
So has Jack Bobridge - they are the only two though.
The 14-strong Australian track team heading to London includes 12 making their Olympic debut.
Only 28-year-old Meares and 22-year-old Bobridge have survived the cut from the Beijing Games.
Meares, who won three Olympic medals, including gold in the track time trial in Athens, has the chance to ride into the history books if she wins a medal.
The Queensland flyer could become the first woman from any country to win four track medals in the Olympics and she can also be the first to medal at three separate Games.
"I am just really happy to have been selected," Meares, who will race in the sprint, keirin and team sprint with three-time world champion partner Kaarle McCulloch.
"It's something that I've been working towards for four years. It's a very emotional moment."
Meares and fellow squad members Shane Perkins, Scott Sunderland, Glenn O'Shea and Matthew Glaetzer all won gold medals in Olympic events held at the recent 2012 World Championships.
Alexander Edmondson, 18, is the youngest in the team after impressing in the Junior World Championship in August last year.
His sister, Annette, is also in the team, the first brother-sister combination to represent Australia in cycling in the Olympics, while Rohan Dennis and Michael Hepburn from Ipswich join Bobridge in the men's endurance squad.
Amy Cure, Melissa Hoskins and Josie Tomic will race alongside Annette Edmondson in the women's team pursuit squad.
"We've named a really exciting group who will be extremely competitive," Cycling Australia national performance director Kevin Tabotta said.
"They have done everything that was asked of them in the lead-up to selection and, although relatively young, have demonstrated they have the talent and maturity to deal with the demands of major competition."
