Cadwell Park is a motor racing circuit in Lincolnshire, England, 5 miles (8 km) south of Louth, England. Sited on former parkland across a steep-sided valley with dips and crests, the circuit features sharp changes in gradient, including one section called The Mountain where bikes can become airborne by up to several feet. Its mix of challenging corners has led to its nickname as the Mini-Nürburgring. wikipedia
