British Paralympic archer Mel Clarke is hoping to improve on her Beijing bronze medal by taking gold at London 2012.
"The ultimate goal is to come out with a gold medal," the Norwich-born former world champion told BBC Radio Norfolk.
"Nobody goes to a Paralympics hoping not to come home with a medal. The honour to represent my county on home soil is incredible."
Compound archer Clarke, who carried the Olympic flame for a stretch in Gloucestershire on Thursday, is hopeful she can use previous Games experience to assist her British team-mates.
"This is my second Games and there's a lot more people in the squad now, it's a lot bigger," she said.
"We're a very close team and any experience anyone can share with somebody else is well worth taking.
"But it's a completely different Games, four years down the road and everything's going to be slightly different."
