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, in the First and Second World War.
The 8020m version of the race course, with elevation change of 252m, started in the city of Trieste, on the modern day Via Fabio Severo, eastbound. In the outskirts, the road is named Via Alfonso Valerio. The course has a lot of fast sweeps, and only one tight hairpin turn, the lefthander at the "Faccanoni" quarry, which is about half way. From here, the course heads north west. In the last quarter, the road is parallel to Trieste–Opicina tramway tracks. The 90 degree right hander "curva dell'Obelisco" leads to the finish at Opicina.
Hill climbs usually have no run off area, with the hill on one side, and descent on the other. In Trieste, the road is also ligned with buildings for much of the bottom part.
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.
