Details have emerged from a 2016 report prepared by the U.S. Anti-Doping Agency on practices by the team, led by decorated U.S. marathoner Alberto Salazar.
British double Olympic champion Mo Farah made his last US track race a special one, running the year's fastest 5,000 metres at the Prefontaine Classic Diamond League meeting on Saturday.
"When I hang up my spikes, nobody will remember number two", said Taylor, who'll have a chance to break Edwards' record in the world-record holder's home country this August at the 2017 IAAF World Championships in London. Also notable was Tianna Bartoletta's runner-up finish in the long jump and 19-year-old Vashti Cunningham's third-place effort in the high jump.
The 34-year-old star, who completed an unprecedented "double-double" of 5,000m and 10,000m gold at last year's Olympics in Rio, crossed ahead of Ethiopia's Yomif Kejelcha in second and Kenya's Geoffrey Kamworwor in third.
But at a news conference for the Prefontaine, Farah faced questions about allegations that paint his team, Nike's Oregon Project, in a bad light. Allegations have also surfaced recently based on information obtained by the hacking group known as Fancy Bears. He said the athletes were from various countries, including Russian Federation and Ethiopia. "It was just a matter of telling the boys 'Look, I'm ready'". It's something the press likes to be able to twist it and add a little bit of spices and add stuff on it.
Farah won the 5,000 meters at the Prefontaine Classic at Oregon's Hayward Field on Saturday in 13 minutes, 0.70 seconds.
America's Tori Bowie, a bronze medallist over the distance at last year's Olympic Games in Rio, blasted to victory in the quickest time of the year in 21.77sec. "I believe in clean sports". You push me, and I'm gonna push back.
The 34-year-old also had British company in the top ten in Andrew Butchart, finishing eighth, with the "double-double" victor and Britain's most successful track and field athlete delighted with the marker he laid down in his second outdoor competition of the season.
Farah said he plans to race in Usain Bolt's farewell meeting in Kingston next month before heading to Europe to run in Ostrava.
Saturday's Prefontaine will be bittersweet.
"I came out here and destroyed my personal best so there are no limits on the rest of the season", Bowie said. "I just have to concentrate on the race and getting the job done". "Last year, I was coming off an injury, wasn't signed with anyone and I had just finished school".
Farah faces a repeat of his Rio 5,000m final, with both silver medallist Paul Chelimo and bronze medallist Hagos Gebrhiwet, 23, in the field. Nine-time Olympic medalist Allyson Felix, who won the event at the 2012 Olympics, was fifth.
"You always want to go out and do your best", she told the young sprinters. A lot of guys saying 'I'm going to do this or that.' But I don't like to do that.
The meet starting Friday night is the only US stop for the worldwide Diamond League series.
Tiernan's time bettered the world championships qualifying mark.
Gabriela Stafford of Canada won the 1,500 in 4:07.43 and American Charlene Lipsey won the 800 in 1:59.87.
