FAILED: Jemima Sumgong
OLYMPIC AND London marathon champion Jemima Sumgong is the latest athlete to fail a drugs test.
The 32-year-old Kenyan runner tested positive for the banned substance EPO. The results were revealed in an out of competition test carried out by athletics' governing body the IAAF.
Sumgong was the first Kenyan to win Olympic marathon gold and was due to defend her London title on 23 April.
She has now been provisionally suspended, and will face sanctions if her B-sample also tests positive.
Last year, Kenya was declared in breach of anti-doping rules, and athletes underwent special testing for Rio 2016.
The East African country was deemed "non-compliant" by the World Anti-Doping Agency, but was reinstated before last summer's Games.
Between 2011 and 2016, more than 40 Kenyan track-and-field athletes failed doping tests.
Among those sanctioned was female marathon runner Rita Jeptoo, 36, who was banned for four years following a positive test for performance-enhancing drug EPO in 2014.
