Title: Ethiopian running coach
Pro: Having studied sports pedagogy in communist Hungary, Kostre has turned the Ethiopian long distance running team into one of the most successful in the world.
Con: He is authoritarian and controlling. Told Haile Gebrselassie, one of the greatest runners of all time, that if he arrived late for the Sydney Olympics in order to treat a nagging injury, he wouldn't put him on the team. " He decided to come with us and he won," Kostre once told TIME. "We respect and love all our athletes if they are disciplined."
