Thunderhill RacewayThis is one of the most popular club racing tracks in northern California. The track has grown in popularity over the last several years and is host to many NASA and SCCA club series races. The 25 Hour of Thunderhill is held there and is the longest endurance road race in the world. The track is configurable and event organizers can choose from several configurations to run. The most typical configuration is counter-clockwise without the T5 bypass. The track was designed to run both directions, so driving clockwise is referred to as "Llihrednuht" or "Thunderhill backwards". 3.0 Miles - 15 Turns - 36' Wide - FIA Standard |
