Alldis finished fifth in the wheelchair 1500m in Delhi
Suffolk's Brian Alldis is targeting Paralympic hand-bike gold, just three weeks after taking up the sport.
Alldis, 24, has made the decision to quit wheelchair racing and is now preparing to take to the Olympic track on a cycle in two years' time.
"All I want is London 2012 gold," he told BBC Radio Suffolk.
"I've been to Beijing and got the experience there. I want to go one step further and get a medal, ideally gold. It would be nice at home."
The Bury St Edmund's competitor finished fifth in the 1500m wheelchair race at the Commonwealth games in Delhi in October, in a year that also saw him compete in the Great North Run half-marathon and Tyne Tunnel 2km.
"I made the change because I needed another adventure. In wheelchair racing I got to my peak, made Delhi, made the Paralympics," he explained.
"I'm a little bit apprehensive about the switch, but other athletes have done it, like Neil Fachie [from athletics] and Jody Cundy [from swimming].
"It's going to be fun, [but] there are going to be some hard weekends ahead."
Alldis waited until returning from Delhi before deciding he would switch to the hand-bike.
But the process started in May this year when he was asked to undergo a lab test with British Cycling.
"They came back saying my results were among the best in the UK, which is really good to hear," he added.
"I've just got to work hard to try and be number one in the world."
A key date for earning qualification at London 2012 will be the Paracycling World Championships, which take place in Denmark in September.
