The 1928 race was the first of many tragedies that befell this venue. Italians Emilio Materassi in a Talbot and Giulio Foresti in a Bugatti were battling around the fast circuit. As they came off the banking onto the left side of the pit straight at 125 mph (200 km/h), one of the front wheels of Materassi's overtaking Talbot touched one of the rear wheels of the Bugatti. Materassi lost control of the car, swerved left, cleared a 15-foot wide and 10-foot deep ditch and ploughed into the unprotected grandstand opposite the pits, killing himself and 27 spectators, and injuring another 26. It was the worst accident in motor racing history and remained so until the 1955 24 Hours of Le Mans. The Italian Grand Prix went on a three-year hiatus (but the alternative non-championship Monza Grand Prix was run in 1929 and 1930) until the 1931 race, held in late May instead of the traditional early September, was won by Giuseppe Campari and Tazio Nuvolari, sharing an Alfa Romeo. The 1931 race was something of an endurance race; it took ten hours to complete. The great Nuvolari won again in a shortened 1932 race, this time held in early June.
