The Court of Arbitration for Sport doubled Kenyan marathoner Rita Jeptoo’s two-year suspension to four years for EPO use, it announced on Wednesday.
The three-member court disqualified her returns dating back to April 17, 2014, a period which includes that year’s Boston Marathon where she set a course record and her win in the Chicago Marathon.
Athletics Kenya initially suspended Jeptoo for two years after a sample she gave in September 2014 was found to contain recombinant EPO. She initially filed an appeal of that decision with CAS but later withdrew it. The International Association of Athletics Federations appealed to CAS to extend the ban to four years.
