Endurance racing is a form of motorsport racing which is meant to test the of equipment and endurance of participants. Teams of multiple drivers attempt to cover a large distance in a single event, with participants given a break with the ability to change during the race. Endurance races can be run either to cover a set distance in laps as quickly as possible, or to cover as much distance as possible over a preset amount of time.
One of the more common lengths of endurance races has been running for 1,000 kilometres (620 mi), or roughly six hours. Longer races can run for 1,000 miles (1,600 km), 12 hours, or even 24 hours. Teams can consist of anywhere from two to four drivers per event, which is dependent on the driver's endurance abilities, length of the race, or even the rules for each event.
Coppa Florio was an Italian car race started in 1900, and renamed in 1905 when Vincenzo Florio offered the initial 50 000 Lira and a cup designed by Polak of Paris. The Brescia race visited the route Brescia-Cremona-Mantova-Brescia. In 1908, the race used the Circuito di Bologna: Bologna-Castelfranco Emilia-Sant'Agata Bolognese-San Giovanni in Persiceto-Bologna. Since 1914 most of the Coppa Florio was co-organized with the Targa Florio near Palermo, Sicilia, running four or five laps, 108 km each.
The Targa Florio was an open road endurance automobile race founded in 1906- the track length of the last decades was limited to the 72 kilometres of the Circuito Piccolo delle Madonie, which was lapped 11 times.
The Mille Miglia was an open-road endurance race which took place in Italy 24 times from 1927 to 1957.
The world's first organized 24-hour automobile race event was held on a 1-mile oval track at Driving Park, Columbus, Ohio on July 3–4, 1905. Beginning on the afternoon of July 3, four cars from Frayer-Miller, Pope-Toledo, Peerless and White Steamer raced for a $500 silver trophy. The winning Pope-Toledo car covered 828.5 miles. A protest was filed by the Frayer-Miller and Peerless teams, alleging the Pope-Toledo was not owned by the driver, instead sent from the factory with an engine built for racing.
