Southern 100 History

History of Southern 100 Racing 

Prior to the 1954 Manx Grand Prix, the Southern Motorcycle Club held their race meetings in the north of the Isle of Man at Andreas Airfield with no suitable venue in the south of the island. As a result of a double win for the locals at the ’54 Manx GP, the club decided there should be a race in the south and held a meeting on what was to become known as the Billown circuit.

It was around this time that the Isle of Man Government decided to build a by-pass around Castletown and this would form an integral part of the new course. It wasn’t all plain sailing though and when the organisers approached Tynwald, the Island’s Government, for financial assistance to run the event, they were initially refused.

TH Colebourn 

On 19th April 1955, the Tynwald agreed to provide £10,000 for the running of the TT and £450 for the Manx GP – but nothing for the proposed Southern 100. Fortunately, local businessman TH Colebourn stepped in with the sum of £100 and the first races were scheduled for 14th July 1955.

This date would prove to be the first time ever that the Southern 100 races took place with the 4.25-mile Billown course the designated venue. And whilst they were initially skeptical, the Isle of Man Government, via the Department of Tourism, soon gave the event their full support.

Bob McIntyre sets first ever 100mph lap 

The first year saw three races for 250cc, 350cc and 500cc machines with perfect weather greeting competitors, organisers and spectators. The main 500cc race was a punishing 24 lap race, the equivalent of just over 100 miles hence the name. The 250cc and 350cc races took place over the shorter distance of six laps.

The meeting received 73 entrants in total with the first ever race, the 350cc race, being won by local rider Derek Ennett. He tried his best to win the 500cc race too but he was 100 yards behind eventual winner Terry Shepherd when a piston collapsed on the final lap.

A year later and Bob McIntyre, who would set the first ever 100mph lap of the TT Course in 1957, was one of the star attractions with a prize fund of £305 on offer to competitors. The tough Scot won the Junior but it was again Shepherd who took the honours in the 500cc category.

The sun of 1955 and 1956 was nowhere to be seen in 1957, when the event was granted ‘National Status’ for the first time, and instead torrential rain was the order of the day. However, the event continued to go from strength to strength over the next decade with more races, including Sidecars, added to the programme and by 1969 it was included in the British Championship schedule.

Solo Sidecar Championships 

That came just a year after the introduction of what is now the premier race of the meeting, the Solo Championship with the three wheelers also getting their Sidecar Championship equivalent.

By then, many of the UK’s leading National road racers had lent their support to the meeting and names like John Hartle, Phil Read, Alan Shepherd, Chris Vincent, Derek Woodman and Dan Shorey were all victorious at some stage.

It soon became popular with the Irish contingent too, riders who were already well familiar with racing on the roads. Len Ireland and Brian Steenson were early winners whilst Ray McCullough was a dominant force in the 1970s. And in 1976, a certain Joey Dunlop made his first appearance at the Southern 100, immediately taking the Solo Championship.

The ensuing decades have seen some of the cream of road racing head to the Billown circuit and illustrious names like Phillip McCallen, Ian Lougher, Brian Reid, Jason Griffiths, Ryan Farquhar, Guy Martin, Cameron Donald and Michael Dunlop along with older brother, William, have all been victorious on numerous occasions And it’s been the same in the sidecars with Lowry Burton, Dave Molyneux, Ian and Geoff Bell, Nick Crowe and World Champions Tim Reeves and Ben Birchall amongst the race winners.

The meeting was soon extended beyond its solitary day and the 12-race programme now takes place over four days, still in its traditional mid-July slot. It is now one of five events in the UK to be sanctioned by the FIM as an International meeting, the others being the Isle of Man TT, the North West 200, Ulster Grand Prix and International Gold Cup at Oliver’s Mount, Scarborough.

The Billown Course has also traditionally hosted two other meetings during the year, the Pre-TT Classic races (6 races) at the beginning of the Isle of Man TT fortnight and the Steam Packet National Road Races (3 races) at the end. However, the new TT schedule for 2023, which sees the Senior take place on the closing Saturday, means the latter will now no longer run.
