The circuit was designed in 1969; it was built from 1970 and 1972, and inaugurated that year. Its initial length was 3.488 km (2.167 miles) and only had a small, open pit area. This version of the circuit hosted three editions of the San Marino motorcycle Grand Prix, from the 1985 season to the 1987 season. In 1993 it was modified for the first time: the track length was increased to 4.060 km (2.523 miles), with the possibility to race both the long and the old short loop; moreover, new facilities and new pit garages were built. It was at Misano during the 1993 Italian Grand Prix that the defending 500 cc World Champion Wayne Rainey's career ended after he fell and suffered a broken spine. Between 1996 and 2001 all facilities were improved further, adding more pits and stands. In 2005, a new access point to the circuit was built, Via Daijiro Kato, in honor of the late Japanese rider, killed during the 2003 Japanese Grand Prix, whose in-season race home was in the Portoverde frazione of Misano Adriatico.

Established in 1955, Road America is located midway between Milwaukee and Green Bay in Elkhart Lake, Wisconsin. Its legendary four-mile, 14-turn road circuit has challenged the world’s best racers for over 57 years and currently hosts over 400 events a year. Of its annual events, 9 major weekends are open to the public which include 3 motorcycle events including the MotoAmerica (AMA FIM) series, 3 vintage car events, Sports Car Club of America (SCCA) events, the United Sports Car Racing Series, the Pirelli World Challenge, and the NASCAR XFINITY Series.
Road America is one of only a handful of road circuits in the world maintaining its original configuration[4] being 4.048 miles (6.515 km) in length and 14 turns. The track features many elevation changes, along with a long front stretch where speeds approaching 200 mph (320 km/h) may be reached. One of the best known features of this course is a turn on the backside known as "the kink".

nicknamed "The Glen", is an automobile race track located in the town of Dix just southwest of the village of Watkins Glen, New York, at the southern tip of Seneca Lake. It was long known around the world as the home of the Formula One United States Grand Prix, which it hosted for twenty consecutive years (1961–1980), but the site has also been home to road racing of nearly every class, including the World Sportscar Championship, Trans-Am, Can-Am, NASCAR Cup Series, the International Motor Sports Association and the IndyCar Series.

Virginia International Raceway (commonly known as "VIR") is a race track located in Alton, Virginia, near Danville. It is less than a half-mile from the North Carolina/Virginia border just outside Milton, North Carolina, on the banks of the Dan River.

VIR offers six track configurations, of which two can be run simultaneously. The "Full Course" is 3.27 miles in length while the "Patriot Course" stretches for 1.1 miles entirely inside the Full Course. The "North Course" is 2.25 miles long and the "South Course" covers a distance of 1.65 miles. Both consist of a portion of the "Full Course" and short connecting sections that connect to portions of the "Patriot Course" to produce the two courses that can run simultaneously. There is a second pit complex that is used only when running the "South Course". The longest configuration, "Grand East Course", is 4.2 miles long, and combines most of the "Full Course" and most of the "Patriot Course" by means of two of the short sections of connecting track used to make the "South Course" and "North Course". There is also another, seldom run, long configuration called the "Grand West Course" that uses the other two short connecting sections between the "Full Course" and the "Patriot Course." Car and Driver magazine has an annual test of fast cars called "The Lightning Lap" using the "Grand West Course".[1] Since the Patriot course is contained completely inside the Full Course, they can be run simultaneously.

The season kicks off in May with a return to the Circuit of the Americas in Austin, Texas.

The Circuit is the only FIA-certified Grade 1 track in the United States, and one of only 26 Grade 1-certified motorsports facilities in the world.

The Circuit of The Americas™ track is a 3.4-mile circuit track with capacity for 120,000 fans and an elevation change of 133 feet. It is ideally situated on a 1000-acre site in southeast Austin.

The 20-turn, counterclockwise track, construction of which began in January 2011, draws inspiration from the best circuits around the world, as well as taking advantage of the site's natural topography to include dramatic elevation changes of up to 40 metres.

There is a steep, uphill run into the hairpin Turn 1, which has become the venue's signature corner. Turns 3 through 6 look not dissimilar to Silverstone's high-speed Maggotts/Becketts; Turns 12 through 15 give a nod to Hockenheim's stadium section; and Turns 16 through 18 will mirror the famous, multi-apex Turn 8 at Istanbul Park.
