The Brainerd International Raceway (BIR) is a multi-purpose racing facility near the coast of the North Long Lake just outside Brainerd, a 2-hour ride away from the Minneapolis-Saint Paul metropolitan area in Minnesota. It began operating under the name of Donnybrook Speedway back in 1968 as a private initiative by the NHRA champion and American Motorsports Hall of Famer George Montgomery. The BIR road course has a 2.5-mile (4.02-km) Competition layout and a longer 3.1-mile (4.9-km) layout known as Donnybrook. The Motorsports complex includes a quarter-mile drag strip that holds the world record of speed in any dragster competition, thanks to the 337.58 MPH (543.28 km/h) reached by Tony Schumacher in 2005.
The Brainerd International Raceway hosts a wide variety of motorsports competitions such as the NHRA Nationals, MotoAmerica Superbike, the F4 US Championship, the TransAm Championship, and many other local club racing events. Winters in Minnesota are some of the coldest in the United States, with subzero temperatures and up to 44 inches of snow all over the place, enough reason for the Brainerd International Raceway to remain closed from November to March. During the rest of the year, racing enthusiasts are welcome to enjoy their favorite sports and even stay in some of the world-class accommodations available at BIR.
La pista de carreras para competencias en el Brainerd International Raceway es un trazado de 2.5 millas (4.0 2 km) que comienza cerca del principio de la recta principal, en la cual los conductores tienen la libertad de apretar con fuerza el pedal de gasolina mientras atraviesan la primera y segunda curva de la pista. La curva número tres va a la derecha 60°, sé que me también por otra curva, la número cuatro, que va a la izquierda 60°. Las curvas cinco, seis, siete y ocho de este trazado son las mismas que en el circuito Donnybrook. En la recta entre las curvas ocho y nueve, el circuito de competencias no cambia su dirección, siguiendo a través de las curvas nueve y 10, curva a la derecha de 60° que devuelve a los corredores a la recta principal.
