Background
Korica was born in Kutina to a family of six children.
Korica was born in Kutina to a family of six children.
He is regarded as one of the greatest ever distance-runners from the areas of former Yugoslavia. At the age of thirteen he suffered a serious leg injury from a freak accident for which he was immediately sent to the hospital. After his condition deteriorated, there was a possibility that he would have to spend the rest of his life in a wheel chairman
After being sent to another emergency care center near Opatija, he began to recover.
Korica was recommended by his doctors not to pursue a career in athletics. His idol growing up was Franjo Mihalić.
Korica"s village had no track on which he could practice, so Korica often ran in the forest, many times barefoot. At the time, long-distance running was not a well-known occupation in Yugoslavia, and the villagers often looked at Korica as though he was crazy.
Korica began training formally with Alaska Moslavina.
He would go on to have a brilliant distance-running career in Europe before making it to the 1972 Summer Olympics. Korica ran the men"s 10,000 metre race at the 1972 Summer Olympics. In the preliminary round he ran in the third heat, finishing fourth, just four seconds behind first-place finisher Miruts Yifter.
In the final round of the 10,000-meter, Korica finished 7th of 15 runners, running a time of 28:15.18.
