Southern 100 History

The first event was held in 1955 as, prior to the 1954 Manx Grand Prix success of Derek Ennett, George Costain and Sid Mizen, the Southern Motorcycle Club held their race meetings at the former RAF station Andreas Airfield. When racing was no longer allowed there and as a result of double win at the Manx, the Southern club decided there should be a race in the south of the Island and to hold a meeting on what was to become known as the Billown circuit.

In the early 1950s, the Isle of Man Government decided to build a by-pass to avoid the town centre of Castletown, and whilst traffic was minimal compared to today’s motorised Island, the by-pass provided an integral part of the new course.

Southern 100 Circuit information

The course start-line is on the outskirts of Castletown and the course includes parts of the primary A5 New Castletown Road, the A28 Castletown to Ballabeg road, the A7 Ballasalla to Port Erin road and the A3 Castletown to Ramsey road.

Start/Finish Line

The Start/Finish Line is one of the fastest parts of the circuit. It has great spectator access including catering outlets and grandstands.

  • Average speed - 175mph
  • Distance 4.25 miles


The first corner on the circuit, with a mass start and a slow entry speed, Ballakeighan sees riders trying to gain valuable positions on the brakes. The corner then leads onto the Ballakeighan straight

  • Average speed - 65mph
  • Distance 0.55 miles

Iron Gate

This comes at the end of the Ballakeighan straight. Iron Gate is a right hand turn shortly followed by a fast left hand turn that leads onto Ballanoris (Joey's Gate).

  • Average speed - 75mph
  • Distance 1.11 miles


Ballanoris is also known as Joey's Gate after the legend Joey Dunlop overshot the corner and rode through the gate into the field.

  • Average speed - 85mph
  • Distance 1.55 miles

Ballabeg Hairpin

Ballabeg Hairpin is the slowest corner on the Billown Circuit. It can be very deceiving for riders, as the camber of the road drags the rider into the corner earlier than they need to turn.

  • Average speed - 25mph
  • Distance 1.55 miles


Ballawhetstone is a fast ride hand bend trailing the town of Ballabeg and leading onto Williams Corner.

  • Average speed - 25mph
  • Distance 1.55 miles

Billown Dip

Not being able to see the exit but sending the bike down a huge dip between the stone walls regardless, Billown Dip is a daring corner for riders.

  • Average speed - 170mph
  • Distance 2.36 miles

Cross Four Ways

The second slowest corner on the circuit and one that usually attracts a large crowd of spectators, Cross Four Ways is notorious for its overtakes and low side crashes.

  • Average speed - 35mph
  • Distance 2.80 miles

Church Bends

One of the most popular locations for fans at the Southern 100, Church Bends has two fast flowing bends around the walls of the Malew Church.

  • Average speed - 70mph
  • Distance 3.10 miles

Castletown Corner

The final corner of the Billown Circuit also gives riders a final opportunity to make a last minute overtake. The corner is also a bridge over the steam railway!

  • Average speed - 30mph
  • Distance 4.03 miles
