LONDON - If Alberto Salazar had hoped that his lengthy denial of allegations that he had been involved in doping would be the end of the matter, he was being wildly optimistic.
On Thursday, Kara Goucher, the American distance runner, accused her former coach of making "false statements and one-sided, partial stories" in his 11,600-word open letter.
She was the star witness in the BBC Panorama documentary about Salazar, who coaches British champion Mo Farah.
The poster girl of American distance running promised to say more after she had competed in the US Track and Field Championships in Eugene, Oregon, this weekend.
The Guardian has also obtained e-mail that appear to contradict Salazar's claims that he terminated the contract of his assistant coach, Steve Magness, because he was not good enough to train elite athletes.
The messages, sent just a month before Magness left the Nike Oregon Project in June 2012, show Salazar was happy for Magness to lead sessions and to become the coach of the American 3,000m steeplechaser Lindsay Allen.
It was Magness who made the most serious allegations against Salazar and Galen Rupp, the 10,000m silver medallist at London 2012 - including claims that Rupp had used testosterone as a 16-year-old.
Jeffrey Brown, the doctor who Salazar says carried out tests to ensure his athletes were not sabotaged by testosterone cream, also appeared to dispute his claims.
In an interview with the US news website ProPublica, which cooperated with Panorama, he said he had not prescribed a controlled substance for Salazar's sons or other research subjects as part of an experiment.
Dr Brown said he was merely advising Salazar on how to conduct research on potential sabotage "in a hypothetical situation".
The massage therapist John Stiner also insisted he was telling the truth when he revealed that Salazar had told him he was taking AndroGel, a banned testosterone gel, for his heart. Salazar had claimed that he told him it was for energy but Stiner told ProPublica: "I told 100 per cent the truth. I'll take 20 lie detector tests. Of course he said I'm lying."
However, Salazar had some cause for cheer on Thursday when Rupp won the 10,000 metres at the US world championships trials - his seventh consecutive national title at the distance.
Rupp timed 28min 11.61sec and will be joined on the US team for August's World Championships in Beijing by runner-up Ben True (28:14.26) and third-placed Hassan Mead (28:16.54).
American record-holder Tyson Gay, 32, meanwhile, found his road to the 100m final will not be an easy one as he was overshadowed by younger competitors in Thursday's opening round.
Trayvon Bromell, 19, equalled the third fastest 100m in the world this year to top qualifying for the semi-finals in 9.84sec. Gay's training partner, Remontay McClain, was even faster, the 22-year-old clocking 9.82sec.
Gay ran in the same heat as McClain and was second in 9.85.
