The Southern 100 road races are held each year on the 4.25-mile Billown Circuit located in the South of the Isle of Man in Castletown.
Known as the friendly races, the Southern 100 was first held in 1955 and currently includes 12 races for various classes. The Southern 100 International Road Races will take place in July 2024. The Southern 100 attracts road racing fans from across the world. A month after the main TT races, it is an ideal event to visit the Island if you have not managed to get your fix of racing during the Isle of Man TT.
