Track and field has been dragged through the ringer since Sebastian Coe took over as president of the International Association of Athletics Federations (IAAF) in Beijing last August on a "zero-tolerance" anti-doping mandate.
Widespread corruption at the heart of the IAAF, involving Coe's disgraced predecessor Lamine Diack, was linked to shocking levels of institutionalised doping in Russia, one of track and field's powerhouses.
In November, the IAAF issued a blanket ban of Russia's track and field team over that state-sponsored doping, ruling that only US-based long jumper Darya Klishina was eligible to compete at the Rio Games, which start on August 5.
Whistleblower Yuliya Stepanova, the Russian 800m runner who lifted the lid on systematic doping fraud in her country, had been hoping to compete after being accepted by the IAAF as a neutral.

But Games organisers, the International Olympic Committee (IOC), said the Olympic Charter does not allow such a gesture even if they have invited Stepanova, who dubbed the decision "unfair", and her husband to Rio as guests.
"This will scare a lot of people, or send a strong message that the sport is serious about cleaning up," Bolt said.
IAAF president Coe added: "I feel the pain that we all feel at the moment because we love our sport. It's been painful to see where our sport is at the moment in public perception."
And so the stage is set for Bolt in his quest for an unprecedented third Olympic treble.
Brushing aside any concerns about the hamstring injury which forced him to withdraw from his country's Olympic trials earlier this month, the Jamaican sprint king ran a solid time of 19.89sec in his first competitive 200m of this season in London last week.
"I'm getting there. I am not fully in shape," said the 29-year-old. "I need more work, but over time I will get there. I thought the cornering wasn't perfect. But I am feeling good.
Ironically, Bolt's closest rival looks like being Justin Gatlin, the 34-year-old American who has served two doping bans and credits his longevity on the track to time spent off it due to his enforced absences.
Bolt warned Gatlin, who won sprint silvers behind the Jamaican at last year's Beijing world championships, that "I am in much better shape, so I won't leave it to the last second."
While the Jamaican and US squads, and in-form Dutchwoman Dafne Schippers, battle it out in the sprints, Britain's Mo Farah will bid to defend his 5,000 and 10,000m from the usual Ethiopian and Kenyan competitors.
"This is my best form (heading into a major event). I am in good shape. I have to keep my feet on the ground. Anything can happen over the next two-and-a-half weeks. I have to stay patient and cool," Farah said.
