Tuhia he haere tonu mo tenei whitianga - I uru a Mihalić ki te marathon
i te 1960 Summer Olympics i Roma, ka mutu i te 12th, i roto i te wa o te 2: 21:52.6. Ko tana wikitoria tuatoru me te whakamutunga o Cinque Mulini i te tau 1961, i mua tata o tana huritau 41, ko tana whakamutunga nui o te ao. I reti a Mihalić mai i te hakinakina i te tau 1966 ma te wikitoria i tana whakataetae whakamutunga, te Kadinjača mini-marathon i Užice.
