The world’s best 1500m runner and the 2019 1500m world champ, Timothy Cheruiyot, has been added to the Kenyan Olympic team to race the 1500m, in a last second switch.  Cheruiyot replaces teenager Kamar Etiang, who finished second at the Kenyan trials. Etiang has recently come into some grief by failing to comply with the Athletics Integrity Unit (AIU) doping measures requiring three out-of-competition tests in the last 10 months, Kenyan athletics officials said.
