ヘルムート・マルコ
Although the public road circuit used for the Targa was extremely challenging- it was a very different kind of circuit and race from any other race on the sportscar calendar. All of the circuit variations of the Targa were made up of rough, bumpy, undulating, narrow and often dusty mountain roads that were very slow and twisty, and each variant had so many corners that lap speeds at the Targa never went higher than 80 mph (128 km/h), as opposed to Le Mans in France, where cars would average 150+ mph (240+ km/h) or the Nürburgring, where cars would average 110 mph (176 km/h). Helmut Marko set the lap record in 1972 in an Alfa Romeo 33TT3 at 33 min 41 s at an average of during an epic charge where he made up 2 minutes on Arturo Merzario and his Ferrari 312PB. The fastest ever was Leo Kinnunen in 1970, lapping in the Porsche 908/3 at or 33 min 36 seconds flat.
