Discus thrower Lawrence Okoye intends to continue in the sport for at least another year - and possibly on to the 2016 Olympics.
The 20-year-old Briton finished 12th in his first Games in London this year, but with a place awaiting him at Oxford University to study law there was some doubt as to whether he would carry on.
But Okoye has committed to discus, even shunning reported interest from NFL and rugby teams.
"I'm going to carry on throwing full-time, definitely for another year, and I think for much longer than that," he told the Daily Mirror. "For me there's unfinished business.
"I see myself being world record holder and Olympic and world champion. It's just going to take a bit of time. I think another year and I'll be ready."
He continued: "The possibility of going to American football was tempting.
"I just think it would be very silly to be ranked fifth in the world for discus at the age of 20 and not carry on.
"I didn't do myself justice finishing 12th [in London].
"But that motivates me going forward towards Rio in 2016. As I say, I have unfinished business."
