Paula Radcliffe has set her sights on competing at the 2012 London Olympics.
The marathon world record holder, who will double up in the 10,000m at this month's world championships, is unfazed that she will be 38 in 2012.
"When the Olympic news came through I was on the massage table but I jumped right off as soon as I heard the word 'London'," said told the Guardian.
"Now I'm figuring out how to keep going until 2012 and also help the new talent to come through strongly."
The Bedford runner will draw on the feat of Carlos Lopes, who at 38 set a world record for the marathon, a year after winning Olympic gold in Los Angeles.
But Radcliffe, who crashed out of last year's Olympic marathon and 10,000m in Athens, will first concentrate on winning a first major track title in Helsinki.
She will line up for the 10,000m on Saturday 6 August, the first day of the world championships.
Radcliffe will then try to emulate the achievement of Emile Zatopek, the only other athlete to win the 10,000m and marathon at the same championships when the Olympics were held in Helsinki in 1952.
The marathon takes place on the last day of the event on Sunday 14 August.
