In April, Rutto was suspended from athletics after his athlete biological passport (ABP) indicated possible drug use. The (ABP) programme collects and compares biological data to detect similarities over time, which can indicate possible doping.
After deeper investigation, (AIU) charged Rutto for doping and banned him from sports for 4 years.
At 2017 World Athletics Championships in London Rutto finished 13th in the 5,000 metres final. The 27-year-old Kenyan holds personal best in the 5000m of 13:03.44.
Rutto's mentor was Patrick Sang, a coach Eliud Kipchoge who on October 12 this year became the first man in history to break 2 hours in the marathon.
Just less than a week ago, Abraham Kiptum, the half marathon World record holder, recieved 4-year doping ban because of abnormalities in his ABP.
Currently, there are 44 Kenyan athletes who are serving a doping ban. Between 2004 and August 2018, 138 Kenyan athletes tested positive for doping.
