(Reporter: Let me get that clearly, every time you went for a race she gave you those tablets?)

"Yes when we went for races."

(Reporter: And when you finished the race did she give you anything?)

"When we went for a race she would give me. Even when I ran in that race she gave me three tablets and I took them. I don't know, they look like capsules and inside it looks like this (points to the floor painted with red oxide)."

(Reporter: And now when she was doing that, didn't you ask what the medicine was for?)

"I was asking her and she was saying it's multi-vitamin. All I knew is that when you are injected is when it is bad. Medicines taken orally are okay, it's injections which are bad."

(Reporter: You used to take the medicine because you knew as long you are not injected you are fine?)

"I just knew they were tablets of multi-vitamin, just that, but injections are drugs that would kill me."

"It's really frustrating to hear that people have been caught but all in all, in our group we normally (think), (that) you know, people dope because they need good performance and after you get good performance what will follow? Money, isn't it? But people forget that money cannot be harvested. So if you want to harvest the money, you need to plant the seeds and what are the seeds? The seeds is (are) hard training, working smart. That is not even working hard but working smart."

29. 07:34 SOUNDBITE: (English) Sarah Ochwada, analyst, lecturer and International Sports Lawyer:

"I think when it comes to the exploitation of Kenyan athletes, over the years it seems to be more rampant because between the year 2012 and now we've seen over 40 Kenyan athletes being banned for doping violations. Now, a very small percentage of that is actually what we would consider very high-profile elite athletes; the rest of them are relatively unknown."

31. 08:10 SOUNDBITE: (English) Sarah Ochwada, analyst, lecturer and International Sports Lawyer:

"The funny thing about Kenyan society is you don't even have to be guilty of a doping violation for society to look at you as a cheat. For so long as you are suspected of doping you become sort of a bad influence or a pariah according to the society around you. Most likely no one will want anything to do with you."

Kenyan athletes comment on the doping crisis that has enveloped the country's track and field programme.

SCRIPTING INFORMATION:

Lillan Mariita's home in the poor, muddy tea-plantation village of Nyaramba in western Kenya is built with winnings from racing on American roads.

Comfortable by village standards, it has sturdy brick walls, new metal roofing, concrete floors, an outhouse, a wood fire for cooking and a small front yard where banana trees and corn grow lustily in the rich, ochre-red soil.

Mariita is one of many second and third-tier Kenyan athletes who competed in races across the globe offering prize money that is powerful bait to the deep wells of poverty and running talent back in Kenya.

Such races attract a workforce of globe-trotting athletes whose methods and honesty now face intense international scrutiny because dozens of them have been busted for doping since Kenya won 11 track and field medals at the 2012 London Olympics.

Mariita was part of a stable of East African athletes in Newport, Kentucky, run by a former elite runner for Russia, Larisa Mikhaylova.

Her runners have won tens of thousands of dollars from smaller races across the American Midwest. But a string of positive drug tests among athletes she worked with put her camp on the radar of anti-doping investigators, who are now looking into her business.

Mariita failed not one but two tests in an eight-month span. Even after Athletics Kenya informed Mikhaylova by email that Mariita was suspended from competition, her agent continued to enter the petite runner for races, winning thousands more dollars before the 27-year-old's second failed test ultimately ended her running career.

Mariita told The Associated Press that Mikhaylova used to give her pills before races, saying "they were vitamins."

"Even when I ran in that race she gave me three tablets and I took them. I don't know, they look like capsules and inside it looks like this," she said, pointing to the red-coloured floor, in an interview with The Associated Press.

After her second failed drug test last July, following a race in Kentucky, Mariita was banned from competition for 8 years. That is the longest punishment of any of the 38 Kenyan runners banned for doping violations since the London Olympics.

With little education and no income from races, Mariita sees no future in her village for her and Lisa, her daughter who was born in the United States.

The two-year-old's father is Jynocel Basweti, another Kenyan runner who worked with the Russian agent. He also tested positive for banned drugs. He has stopped racing since serving his two-year ban.

Basweti told AP that Mikhaylova "was giving me some tablets."

Speaking to AP, Mikhaylova emphatically denied ever giving drugs to athletes.

Mikhaylova boards runners from Kenya and Ethiopia in a two-story house in a working-class neighbourhood in Newport, a suburb of Cincinnati, Ohio. It has a picture of the Kremlin hanging over the fireplace in the living room.

She described herself as nothing more than a service provider for East African athletes far from home, identifying and entering them in races she thinks they can win and looking after their other daily needs, in exchange for her 15-percent cut.

She told the Associated Press that she never gave pills to Mariita.

"All my runners, they take responsibility for their selves. They have to take responsibility for their selves," Mikhaylova said.

The International Association of Athletics Federations (IAAF), which governs the sport, says it is looking into Mikhaylova's camp, working together with the US Anti-Doping Agency (USADA)

In the United States, some race directors are also taking precautions. Without waiting for the outcome of the IAAF probe, some say they are already giving Mikhaylova's athletes a wide berth.

When Mikhaylova emailed race organisers in Indianapolis last May to enter two athletes for their Monumental Mile, they responded with a copy of their new anti-doping policy. It specifies that athletes won't be eligible for prize money if they work with agents who have had two or more runners banned.

Many of Kenya's runners busted for doping were largely unknown journeymen and women, like Mariita, who pound out a living from races around the world, chasing cash prizes that can lift families out of poverty in Africa.

The majority took banned substances close enough to races for traces to still be detectable when they competed - an amateur mistake that former track stars like Marion Jones and others with access to savvy coaches and doctors, never made.

Ronald Rutto fits this bill. He was the world junior steeplechase champion in 2004.

But he tested positive in 2012 for the endurance-boosting hormone EPO at a race in Austria and was banned. He says he got an injection from a Kenyan pharmacist before he left for that overseas race, and that his life has gone downhill since.

His and Mariita's stories represent the underbelly of the top-to-bottom doping crisis in Kenya's thriving but ill-regulated running industry.

Some Kenyan athletes fear their country might be barred from international competition, like Russia, if the problem isn't solved. The World Anti-Doping Agency has given Kenya until 5 April to fall in line with global anti-doping rules.

World-beating athletes like Eliud Kipchoge are frustrated by the damage that doping is doing to Kenya's reputation.

He and other elite runners train and live together in Spartan conditions in their high-altitude camp in western Kenya, even taking turns with daily chores like mucking out toilets and doing the washing up. They say they are regularly drug tested.

Kipchoge, who has won the London, Berlin and Chicago marathons, thinks dopers are being short-sighted in pursuit of fame and fortune.

"People forget that money cannot be harvested," he says. "If you want to harvest the money, you need to plant the seeds. And what are the seeds? The seeds are hard training, working smart."

Dust clings to his eyelashes and hairs on his legs during a punishing training run through the forest that he and dozens of other athletes from separate training camps meet up for before dawn. By training together, the runners spur each other on.

They also party together before major competitions, buying sodas and roasting a sheep in a celebratory send-off. They are already planning their next one: before the Rio de Janeiro Olympics in August.
