Laguna Seca

The track was constructed in 1957 with $1.5 million raised from local businesses and individuals. It occupies part of the US Army's Fort Ord, a former maneuver area and artillery target range. The decision to build Laguna Seca followed the abandonment of the Pebble Beach Road Races due to safety concerns. The inaugural race took place on November 9, 1957, with Pete Lovely winning in a Ferrari. In 1974, the property was transferred to the Monterey County Parks Department, where it remains a part of the park system.

Initially, the track measured 1.9 miles (3.1 km). This configuration lacked the current infield section, featuring a straight that ran from the vicinity of present-day Turn 2 to the area of current Turn 5. During this period, Laguna Seca hosted events for series such as the USRRC, Can-Am, Trans-Am, and Formula 5000.

The circuit's most distinctive feature is the "Corkscrew" (Turns 8 and 8A), a challenging combination characterized by a blind crest and a 59-foot (18 m) drop in elevation. This section has been the site of memorable racing moments, including Alex Zanardi's 1996 last-lap pass of Bryan Herta. Other corners bear the names of racing luminaries: Turn 2 is the "Andretti Hairpin," named for Formula 1 World Champion Mario Andretti; Turn 9 is "Rainey Curve," honoring 500cc Grand Prix motorcycle racing World Champion Wayne Rainey; and the straight between Turns 6 and 7 is the "Rahal Straight," named for four-time consecutive Champ Car race winner Bobby Rahal.

Laguna Seca has undergone significant modifications to meet evolving safety homologation requirements from bodies like the FIM and FIA. In 1988, the track was extended to its current length by incorporating the infield area (present-day Turns 3, 4, and 5) to satisfy the FIM's minimum track length criteria for MotoGP events. In 2006, the original media center was demolished to create additional runoff space at Turn 1. Also in 2006, the "hump" at the top of the Rahal Straight was flattened to better accommodate MotoGP riders, though some suggest this change may have increased wind effects on motorcycles. Further safety enhancements have included expanding gravel pits around turns 1, 2, 5, 6, 8, 9, and 10 for increased runoff.

The track has a rich history of hosting diverse racing disciplines, including IndyCar, IMSA GT, the Superbike World Championship, and MotoGP. This history includes significant incidents. In 1999, Uruguayan driver Gonzalo Rodríguez tragically died during a CART practice session following a crash at the Corkscrew, which prompted the installation of runoff at the end of the Rahal Straight. In 2015, riders Dani Rivas and Bernat Martínez lost their lives after an accident during a MotoAmerica event.

Beyond professional motorsport, Laguna Seca is the venue for the annual Rolex Monterey Motorsports Reunion, a gathering for historic automobiles, and the Sea Otter Classic, a major cycling festival. The raceway has also hosted non-sporting events, such as five concerts by the Grateful Dead in 1987 and a mass celebrated by Pope John Paul II that same year, attended by 72,000 people.

Currently operating as WeatherTech Raceway Laguna Seca, the track's day-to-day operations are managed by A&D Narigi Consulting, LLC. While unofficial lap records have been set by drivers such as Marc Gené (1:05.786 in a Ferrari F2003-GA in 2012) and Sébastien Bourdais (1:05.880 in a Champ Car in 2007), Christian Lundgaard holds the unofficial qualifying record with a time of 1:06.4610. The track is also featured in popular racing video game series like Gran Turismo and Forza Motorsport.

In 1989, Laguna Seca was considered as a potential venue for the United States Grand Prix, following the sport's departure from Detroit. However, Formula One organizers ultimately chose Phoenix, deeming Laguna Seca too remote and too small to accommodate a Formula One event.
