The troubles of track and field, along with its triumphs, will be on display when the U.S. Olympic trials begin Friday.

Tim Montgomery and five other athletes with doping accusations pending will be allowed to compete, the head of USA Track and Field said yesterday.

"The law of the United States is quite clear," USATF Chief Executive Officer Craig Masback said. "It says unless someone has received a full due process hearing and found to be ineligible, they must be allowed to compete."

That means 100-meter world record holder Montgomery, sprinters Chryste Gaines and Michelle Collins, twins Alvin and Calvin Harrison, and distance runner Regina Jacobs are free to enter the U.S. trials.

Montgomery and Gaines are entered in the 100, Collins and the two Harrisons in the 400, and Jacobs in the 1,500 at the trials, to be held in Sacramento.

Montgomery, Gaines, Collins and Alvin Harrison have been told by the U.S. Anti-Doping Agency there is evidence they have committed doping offenses, even though they have not tested positive.

Calvin Harrison and Jacobs have tested positive for banned substances but are contesting those results and are awaiting hearings on their cases. The trials go through July 18, with the top three finishers in each event making the U.S. team for Athens, provided the athletes have met Olympic qualifying standards.

Armstrong Named to U.S. Team

Lance Armstrong was among the eight road riders formally chosen for the Olympic team by USA Cycling.

Armstrong, seeking a record sixth straight Tour de France victory, is joined on the men's team by his U.S. Postal Service teammate George Hincapie -- who, like Armstrong, will ride in the Olympics for the fourth time.

Tyler Hamilton, an Olympian in 2000, also is on the men's roster, as are first-time selections Bobby Julich and Jason McCartney. The women's road team is composed of Christine Thorburn, Kristin Armstrong and Dede Barry.

El Guerrouj, A. Johnson Win

Hicham El Guerrouj rebounded from his startling loss in Rome last week, winning the 1,500 on a fast, new track at the Athletissima Super Grand Prix in Lausanne, Switzerland.

El Guerrouj, so shaken by last week's end to a 29-race victory streak in the distance that he considered skipping the Olympics, won in 3 minutes 32.30 seconds.

Allen Johnson (Lake Braddock) won the 110-meter hurdles, finishing in a world season's best time of 13.05 seconds.

"It's a very fast track. I like it," Johnson said, referring to the week-old surface.
