MADRID (AP) -- The Spanish athletics federation says former Olympic 100-meter champion Justin Gatlin will compete in Saturday's Madrid meet.
Gatlin continues his preparations for next month's worlds in Daegu, South Korea, by lining up in the 100 against Walter Dix, who edged Gatlin at the American trials last month. British sprinter Dwain Chambers will also take part, according to a statement on the federation's website Tuesday.
Gatlin won gold at the 2004 Athens Olympics, and won the 100 and 200 at the Helsinki worlds one year later. He returned from a four-year doping ban last year.
