The Masaryk circuit (Czech: Masaryk?v okruh) or Masarykring, also referred to as the Brno Circuit, refers to two motorsport race tracks located in Brno, Czech Republic. The original street circuit was made up of public roads, and at its longest measured 18 miles (29 km). In 1949, events such as the Czechoslovakian Grand Prix attracted top teams and drivers. The track is named after the first president of Czechoslovakia, Tomá? Garrigue Masaryk. Racing on the old roads ended after 1986, when the new (current) circuit was opened.
The annual Motorcycle Grand Prix of the Czech Republic is the circuit's most important event. It is held here since 1950 and is the most famous motor race in the Czech Republic. Championship is part of the World Grand Prix since 1965.
The Czech Republic Motorcycle Grand Prix is more of a promoter event than a profit-raiser itself. Since tobacco advertising has been banned in 2007, it is common among the other MotoGP events. The Brno Circuit is historically one of the oldest circuits, on the place were also held the most motorcycle championships in history after the TT Circuit Assen.
The original layout ran anti-clockwise on approximately 29 km (18 mi) of public roads in the outskirts of Brno, where the start/finish was located in Bosonohy. The circuit went east past Kamenny and then went north past the Bohunice University Campus in Kejbaly, and went through the villages of Libusino, Kohouvotice and ?eb?tín, out to Ostrovacice, through Veselka and back through a series of fast straights and kinks. From 1930 to 1937, the Masaryk circuit races attracted some of the top drivers and teams.
On September 25, 1949, the race was held for the first and the last time in Czechoslovakia as part of the Grand Prix motor racing (later evolved into Formula One). The Czechoslovakian Grand Prix in 1949 was run clockwise on a shorter 17.8 km (11.1 mi) layout, which turned right at Veselka, bypassed Ostrovacice and entered ?eb?tín from the south rather than the west. In spite of a crowd in excess of 400,000 people, this would be the last Grand Prix for cars on the old circuit.
Beginning in 1950, the circuit played host to the Czechoslovakian motorcycle Grand Prix, which became a world championship event from 1965. The circuit had been again reduced in length to 13.94 km (8.66 mi) in 1964, completely bypassing ?eb?tín and using a new through-road that went to Kohoutovice quicker. The European Touring Car series visited in the 1980s, by which time the circuit had been finally reduced to 10.92 km (6.79 mi) in 1975, which exited Kohoutovice from the south and bypassed Libusino and Kejbaly and went right through Kamenny and rejoined the main road back to Bosonohy.
The current permanent road racing circuit was opened in 1987. It lies north of Kyvalka, within the bounds of the circuit used in the 1930s, but not incorporating any of the public roads. The motorcycle race moved to the new circuit and regained its status as a round of the world championship. A World Sports Car Championship race was held in 1988, and a round of the A1 Grand Prix series in 2006. It is also the location of the 24H Epilog of Brno (previously 6 Hours of Brno).
