Circuito Guadix, officially known as Circuito Mike G Guadix, is a motorsports facility located near Granada, Spain, nestled in the foothills of the Sierra Nevada in Andalusia. The circuit opened in 2002 and was significantly redesigned by Clive Greenhalgh and reopened in mid-January 2007. The facility was fully upgraded and resurfaced in July 2024 with premium low-abrasion asphalt.

The circuit measures approximately 3.0 to 3.2 kilometers in length and features 14 corners ranging from tight hairpins to sweeping bends. The main straight extends 750 meters, providing excellent acceleration opportunities. The facility can be configured into multiple layouts - the main and alternative circuits can be split and used in reverse, offering a total of 4 circuit configurations. The pit area features 20 professional boxes equipped with technical support capabilities, timing equipment, and data analysis systems. A unique feature of Circuito Guadix is the lack of noise restrictions, allowing vehicles to run 24 hours a day, 7 days a week. The circuit is extensively used by many companies including Renault Motorsport, KTM, Superbike Magazine, and approximately 95% of all British Superbike factory teams for testing and development work, making it one of the most popular testing venues in Europe.
