TRIBUTES have poured in from the world of sport for marathon world record-holder Kelvin Kiptum, who was killed in a car accident on Sunday at the age of 24.

The Kenyan long-distance runner, who became the first athlete to run a marathon in under two hours and a minute in Chicago last October, died when the car he was driving was involved in a collision in Kaptagat, south-west Kenya, at around 11pm local time.

His coach Gervais Hakizimana was also pronounced dead at the scene, while a third person was taken to hospital.
