Barely hours after breaking the 10,000m world record at the Rio Games, Almaz Ayana had to fend off allegations that "she was not clean".
The Ethiopian obliterated the 23-year-old world record held by China’s Wang Junxia, chopping off 14 seconds on Friday as she won in 29 minutes, 17.45 seconds to claim her first Olympic gold medal.
Kenya’s Vivian Cheruiyot also ran a personal best of 29:32.53 to claim silver while Ethiopian Tirunesh Dibaba was third.
However, not long after the race some of her rivals raised questions about her achievement with American Emily Infeld, who finished 11th, admitting she was never in the race.
"There’s no way I could compete with that, there’s no way I could run with that," she said.
Sweden's Sarah Lahti finished 12th in a national record 31:28.43, and she went even further as she questioned whether or not the 24-year-old Ayana was clean.
"I don’t believe she is 100%," she told Expressen after the race. "It appears to be a little too easy for her. One cannot spot any facial expressions, she just presses on, while the rest of us are fighting for our lives at the rear. There cannot be that much of a difference. I cannot say that she is not clean, but there is little doubt."
However, Ayana says she has nothing to hide.
"Three basic things. I did my training, specifically (for the) 5000 and 10000. Number two, I praise the Lord. God has given me everything, every blessing. My doping is my training. My doping is Jesus. Otherwise. Nothing. I am crystal clear," she said through a translator.
