Sunday track preview

ATHENS - The men's 100 meters and women's marathon finals take center stage as two of the classic Olympic events are contested. Defending Olympic gold medalist Maurice Greene (Granada Hills, Calif.) and top contenders Shawn Crawford and Justin Gatlin, both of Raleigh, N.C., will try to keep Jamaica's Asafa Powell off the medal stand.

In the marathon, American record holder Deena Drossin (Mammoth Lakes, Calif.), Olympic Trials champion Colleen DeReuck (Boulder, Colo.) and former NCAA track champion Jen Rhines (Ardmore, Pa.) make the 26.2-mile trek from Marathon to Athens' Panathinaiko Stadium, the stadium that hosted the first modern Olympic Games, in 1896.

Olympic Trials champion Jaime Nieto (Chula Vista, Calif.) and Matt Hemingway (Littleton, Colo.) compete in their first Olympic men's high jump final, while Walter Davis (Baton Rouge, La.) and Kenta Bell (Chula Vista, Calif.) represent the U.S. in the men's triple jump final.

Qualifying rounds continue in the men's and women's 400 meters, women's 400m hurdles and men's 1,500 meters, while the first two rounds of the women's 100-meter hurdles hit the track.
