From the Oxford companion to Motorsports Racing "The oldest motor-cycle racing circuit still in use is the Snaefell Mountain Course over which the Isle of Man Tourist Trophy races are run. Starting at the town of Douglas on the south-east coast, the course takes a wide sweep to the west and north to enter the town of Ramsey on the north-east coast and thence return to the starting point, each lap measuring 37 3/4 miles (60.7 km) and taking in over 200 bends while climbing from sea level to an altitude of over 1,300 ft (396 m). This circuit is the epitome of the natural road course, all the roads used being ordinary public highways closed for the racing and practice sessions"
