Trieste-Opicina hillclimb
Trieste-Opicina is a hillclimb up the Opicina hill in Trieste, northeastern Italy. Also known as Albo d'Oro automobilistico. The race was suspended twice, around First and Second World War. After a serious crash of Austrian Herbert Jerich in a Ford Escort TC and subsequent safety concerns the race was cancelled after its 1971 edition. From 2017, the historic race was recreated as a tour on closed roads around Trieste.
