Kenya is famous for its long and middle-distance running prowess, but it has been caught up in a series of doping scandals over the last five years, a period over which around 60 of its athletes have been sanctioned for anti-doping violations.
A World Anti-Doping Agency (WADA) report in September 2018 said 138 Kenyan athletes tested positive from 2004 to August 2018.
