Sprint star Xavier Carter is aiming for a fast start to his first full season as a professional when he races at the Norwich Union Grand Prix on Saturday.
The 21-year-old American - who clocked world-class times at 100m, 200m and 400m in 2006 - is running the 400m at the National Indoor Arena.
Carter stormed to international prominence last summer with a breathtaking display at the Super Grand Prix meeting in Lausanne, Switzerland.
In only his second race outside of America, Carter won the 200m in 19.63 seconds, a time for the distance only bettered by Michael Johnson's extraordinary 19.32 at the Atlanta Olympics in 1996.
