Editing Brno Circuit (section)

==Original circuits==
The original layout ran anti-clockwise on approximately {{convert|29.194|km|mi|abbr=on}} 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 [[Žebětín]], 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.<ref>Ivan Margolius, 'Czechoslovakia's First Circuit', ''The Automobile'', August 2019, pp. 48 - 54</ref>

On [[1949 Grand Prix season|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]]).<ref>{{cite news |title=Formule 1 na území Česka?

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 [[Czech Republic motorcycle Grand Prix|Czechoslovakian motorcycle Grand Prix]], which became a world championship event from [[1965 Grand Prix motorcycle racing season|1965]]. The circuit had been again reduced in length to {{convert|13.941|km|mi|abbr=on}} in 1964, completely bypassing Žebětín and using a new through-road that went to Kohoutovice quicker. The [[European Touring Car Championship#ETCC 1963-1988|European Touring Car]] series visited in the 1980s, by which time the circuit had been finally reduced to {{convert|10.921|km|mi|abbr=on}} 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.
