His sudden death has left Kenya, and the wider athletics community, reeling.
"An athlete who had a whole life ahead of him to achieve incredible greatness," said Kenyan marathon legend Eliud Kipchoge.
The 24-year-old was driving from Kaptagat to Eldoret around 11 pm (2000 GMT) on Sunday when the car rolled, killing the young sensation and his Rwandan coach Gervais Hakizimana.
