Kenya have decided not appeal against the one-year ban handed to former three-time World half-marathon champion Susan Chepkemei.

Athletics Kenya secretary David Okeyo said the 32-year-old athlete, who tested positive for salbutamol last September, was lucky to have escaped with a lenient sentence because of her acceptance that she had taken a medication containing the banned drug to treat pneumonia.

"Chepkemei was very open and that is why we gave her a one-year suspension," said Okeyo. "Some athletes are punished for four years or even for life."
