Marathon world record-holder Kelvin Kiptum, who was set to be a superstar of long-distance running, has died along with his coach in a car crash in Kenya. Kiptum was 24, and the world record he set last year at the Chicago Marathon was ratified by international track federation World Athletics just last week. Kiptum, who was Kenyan, and his Rwandan coach, Gervais Hakizimana, were killed in the crash late Sunday. Police said their vehicle was the only one involved in the crash and Kiptum was driving when it veered off a road and into a ditch before hitting a tree.
