In an interview, Coe launched a fresh plea for athletes to turn informants should they encounter doping, saying it was a “historic moment” for athletics.
Stepanova herself served a two-year doping ban before she and her husband Vitaly made startling revelations about state-sponsored doping in Russian athletics.
Associated, widespread corruption with the International Association of Athletics Federations (IAAF) plunged the body into its worst-ever crisis, just as Coe was installed as president in place of now-disgraced Lamine Diack.
Russian athletes were promptly suspended from international competition in November and now face a race a raft of criteria to meet before even being in with a chance to compete at the Rio Olympics.
But Stepanova, now exiled in the United States, was handed the chance to compete as a “neutral” as recompense for her speaking out on the systematic doping at the heart of Russian athletics.
“She fulfilled the eligibility criteria set down by the IAAF taskforce and anti-doping review board and the invitation was at the behest of European Athletics,” Coe said of Stepanova, who tore a ligament in her heel during her 800m heat on Wednesday and was later disqualified.
“Without her support and the evidence she gave the taskforce, we would not have understood as much about the challenge to be confronted.
“You have to be consistent. If you are asking athletes to step up to the plate and not just be commentators sitting in the background ... then I think you have to say that those that are prepared to do that should be recognised for that.
“The athletes have a very clear role to play. I don’t mind athletes showing passion and being outspoken about this, but they also have a responsibility to help us and position themselves as part of the solution rather than just sitting there and saying ‘Well I didn’t get a medal because....’ “They do need to be in a position where they’re really prepared to stick their heads above the parapet.
They know more about it than any of us. They’re there, at the side of the track, they’re in the training groups, they know the coaches not doing it with integrity. They can help us and that’s really important.”
Coe added of Stepanova’s muted comeback: “I don’t want this just to be the end of the story.
“And I make this offer to all athletes.
If you think you can help us get through this pathology quicker, if you can help us understand the nature of the challenge that we’re dealing with... it’s a golden opportunity that is not necessarily going to present itself again for our sport to grab this moment, this is a historic moment.
This is a really important moment, not just for my sport but sport more broadly.”
