NAIROBI (Reuters) - Kenya’s former 1,500 metres world champion Elijah Manangoi has been handed a two-year ban for anti-doping violations after missing three tests under whereabouts rules, the Athletics Integrity Unit (AIU) said on Friday.Manangoi, who will be ineligible to compete at next year’s Tokyo Olympics, was provisionally suspended in July and the AIU said his ban comes into effect from Dec. 22 2019 which was the date of the third “whereabouts failure”. The ruling means the disqualification of all Manangoi’s competitive results since then “with all resulting consequences, including the forfeiture of any titles, awards, medals, points prizes and appearance money,” AIU said in its statement. Manangoi’s ban comes after American 100 metres world champion Christian Coleman was also suspended for two years last month for breaching whereabouts rules. Manangoi joins a list of Kenyan athletes who have been sanctioned in recent years, including 2008 Olympic 1,500m champion Asbel Kiprop, former Boston and Chicago Marathon winner Rita Jeptoo and 2016 Olympic marathon champion Jemimah Sumgong.
