The 21-year-old IAAF female athlete of the year went undefeated this year in the 400m and moved up to seventh on the all-time list after posting 48.70 seconds at the Athens World Cup.

She told the Jamaica Observer that Marita Koch's world record of 47.60 is out of her reach for the time being but she believes she can become the third fastest woman ever soon.

Olympic speculation is harming athletes, says Games chief Bach

"It's not one of my targets for 2007, it's one of my targets before I end my career, probably over the next four years or so," Richards revealed.

"But I'm hoping to challenge and to pass Marie-José Pérec's time of 48.2 next season, so that's my goal."

Richards has also made it clear that victory in August's World Championships in Osaka is her goal for 2007 after she had to settle for silver in Helsinki last year.

She commented: "Year before last I was able to win every race except for the World Championship so for me, if I can go undefeated and bring home the gold medal in the World Championship, that would make my season perfect."

But Richards admitted that she will face plenty of competition next season.

"Tonique (Williams-Darling) was out this year but she'll probably come back, I can't discount Ana Guevara and Shericka (Williams) and Novlene (Williams) are both young so they should come back next year even stronger," she mused.
