American athlete Galen Rupp qualified for the World Championships after weeks of doping allegations against him.

Rupp will compete in both the 5,000 metres and 10,000 metres in Beijing in August after his performances in the US trials in Oregon.

Rupp finished third in the 5,000m yesterday behind winner Ryan Hill and Benjamin True having won the 10,000m on Thursday.

The 29-year-old was featured in a BBC Panorama documentary broadcast earlier this month which claimed coach Alberto Salazar had given him the banned anabolic steroid testosterone in 2002, when he was 16 years old.

Both have denied the allegation with Salazar, who also coaches British Olympic champion Mo Farah penning a 12,000-word open letter last week addressing each accusation in detail. Salazar, meanwhile, has revealed he was never in doubt that Farah would stick by him.

Salazar is reportedly under investigation by the US Anti-Doping Agency with investigators questioning athletes at the Nike Oregon Project, leaving open the possibility that double Olympic champion Farah could be quizzed as well.

There is no suggestion of any wrongdoing on the part of Farah. The 32-year-old confirmed that he was sticking by Salazar and the coach does not believes there was ever a chance he would leave.

“There was never any doubt in my mind he was going to stay,” he told the Telegraph. Farah is to return to the track on July 9, for the first time since the allegations broke. Organisers of the Diamond League meeting in Lausanne say Farah will compete in the 5,000 metres.

He is also due to run in the Diamond League meeting in Monaco on July 17.
