PROPOSED REVISED PRACTICE & RACE SCHEDULE FOR SOUTHERN 100 ROAD RACES 2025
Southern 100 Racing, promoters of the Isle of Man Steam Packet Company Southern 100 Road Races are proposing to amend the Practice and Race Schedule for the 2025 Road Races, which will be held Monday to Thursday 7th – 10thJuly.
Subject to the Road Closing Orders being approved it is anticipated that Practicing will commence on the afternoon of Bank Holiday Monday 7th July, between 1.45pm and 4.00pm.
Two contingency periods are proposed, the first on Wednesday 9th July between 1.15pm and 3.15pm, only to be used if any of the practice sessions are lost on Monday or Tuesday.
The second contingency period is for Thursday evening, between 6.00pm and 8.30pm, again only to be actioned if racing on Championship Day is lost.
Southern 100 Race Secretary said: ‘Safety is the highest priority, and practice is a very important component of the event, and we decided that an additional session on the Monday afternoon would ease the pressure on the evening session, especially for newcomers to the races.

The Roads Closing Order being requested is as follows:

History :
The Pre-TT Classic Road Races came into being in 1988 at the request of the then TT organisers, the then Auto Cycle Union, Classics having first appeared on the Billown course twelve months earlier at the popular Southern ‘100’ Road Races.’ The first TT Classic Races were held on the 31st May1988, the meeting consisting of four races, 250cc/350c; 500cc; Unlimited and Sidecars and attracted 115 entries in all.
Honour of being the first race winner went to Graham Godward of Royston in Hertfordshire, riding a 350cc Aermacchi, whilst the 250cc category was dominated by ‘local’ classic man Mike Cain from Onchan on his 250cc Suzuki. Dave Pither, Seeley Matchless took the 500cc race from Richard Swallow on Syd Lawton’s Aermacchi with Alan Dugdale third. Riding a BSA Metisse, Stroud’s Robert Price finished first in the Unlimited race, whilst the controversial MV Agusta sidecar outfit of Mark Kay and Richard Battisson took the chequered flag in the final race of the day. The Classics had arrived at Billown!
Thirty plus years on, the Blackford’s Pre-TT Classic Road Races is rated as one of the most popular and ‘must do’ events in the annual Classic calendar attracting well over 250 entries for its nine-race event.

Pre-TT Classic Road Races Tickets :
The Pre-TT Road Races is a free event. Spectators can visit and find any number of superb vantage spots (for free) around the 4.25 miles of the circuit. There are also a couple of grandstands run by the Southern 100 Club, they are very reasonably priced and if you fancy a guaranteed seat for the day they are a great way to go.
Even though the event is free, it is important to support the sport and one way to do this is to visit the Merchandise Tent, or the Club Hall or Burger van. The breakfasts are great and really well priced! Programmes are also available and are filled with interesting articles, stories, photographs and information about the event. Programmes are available for sale at the circuit.
The Pre-TT Classic Road Races Circuit shares its asphalt with the Southern 100. The circuit is at Billown, Castletown in the South of the Island and is 4.25 miles per lap.

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 Andreas Airfield.
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.
The first meetings to set up the organisation were held in the Station Hotel, now the Viking, in Castletown, which is where the Ennett family lived. This band of gentlemen with foresight also used to meet on a Sunday morning in the Control Tower at Ronaldsway Airport, with Theo Watterson. In between landing planes, the time was taken up planning the Southern ‘100’!
Amongst the first committee were, George Costain and Joe Mylchreest, who officially measured the circuit, using the official ‘chain’ measure (22 yards) and walked around the course measuring down the centre line of the road. The total official distances was, and still is 4.25-miles.
Southern 100 Racing took over the organisation of the Southern 100 Races in 1981, the Southern Motor Cycle (IOM) Club having taken to decision to separate their two sections, road racing and off-road. However it was the same team at the helm and the races, and the event has grown in stature over the forty years of the present organisers to the reputation the event is held in today.
Since the first race on Thursday 14th July 1955, the 350cc won by Derek Ennett a total of 604 races have been run over the Billown Course, including 145 Sidecar races, with 108,749 racing laps completed, a racing distance of 461,911.520 miles at the end of the 2022 meeting.

Southern 100 Tickets :
As was the norm with most road races post Covid spectating at the Southern 100 still remains free around the Course. There are still prohibited and restricted areas, however around the 4.25 miles there are many excellent vantage points.
The Club also has a number of Grandstands available which offer seating and other facilities such as hot food / drinks, and toilets. Full details of the Grandstands can be found here and these are an excellent way to increase your comfort and support the Club. Tickets start at £5, which to be honest is an absolute bargain!
Isle of Man Southern 100 Circuit and Map :
The Course is 4.25 miles in length and has an average width of 25 feet with right- and left-hand bends. The road surface is tarmacadam. All races will be run in a clockwise direction of the course.
Southern 100 Vantage Points :
There is over 4 miles of circuit to watch the action from, with plenty of holes in the hedges to peek out from from the most notable Vantage Points are :
Start/Finish Line (0/4.25 Miles) Line the fencing down the iconic Colas Billown Circuit Start/Finish line or enjoy the comfort of the grandstand. You will get to see the spectacle of mass start road racing and see who crosses the finish line first. The grandstand is priced at £5 for Monday, £5 for Tuesday, £10 for Wednesday and £15 for Thursday.
Winning Enclosure Our ‘paddock grandstand’ is covered so will keep you sheltered from any rain or sun (we can be hopeful)! The grandstand is priced at £5 for Monday, £5 for Tuesday, £10 for Wednesday and £15 for Thursday.
Ballakeighan Corner (0.55 Miles) Ballakeighan is the first corner on the circuit. Bikes pile into the corner on the first few laps after the mass start. The corner then leads onto Ballakeighan straight.n.
Unfortunately we are no longer able to offer fans the opportunity to get to Ballakeighan from the holding area as we no longer have access to the drive way of Balladoole Mansion. View details here.
Iron Gate (1.11 Miles) Iron Gate comes at the end of the Ballakeighan straight. It is a right hand turn shortly followed by a fast left hand turn that leads onto Ballanorris (Joey’s Gate). The Colas Grandstand is also located here with a great view all the way down Ballakeighan straight and of Iron Gate. The grandstand is priced at £5 for Monday, £5 for Tuesday, £10 for Wednesday and £15 for Thursday. We also have Funky Foods located here for all of your catering needs! There is of course also a couple of toilets.
Ballabeg Hairpin (1.55 Miles) 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. There is a public toilet available here.
Cross Four Ways (2.80 Miles) Cross Four Ways is notorious for its overtakes and slow speed low side crashes. It is the second slowest corner on the circuit and usually attracts a large crowd of spectators. Laura and the team from The Barrister Van will be on hand all weekend to keep you refuelled and there is also some toilets.
Church Bends (3.10 Miles) Church Bends is one of the most popular locations for fans. With two fast flowing bends around the walls of Malew Church. There is plenty of parking back again this year (in the back field accessed through the normal gate entrance). There is toilets here too.
Castletown Corner Watch all of the last corner action from the School Hill Grandstand. Our catering team will also be on hand to feed you. There is also public toilets here. The grandstand is priced at £5 for Monday, £5 for Tuesday, £10 for Wednesday and £15 for Thursday.
Southern 100 Parking :
Car Parking for the Southern 100 Motorcycle Show is available in the ‘Day Paddock’ adjacent to the Race Paddock with overspill parking available at the IFGL Car Park close by.
Other ‘Non Official’ Parking Spots are available, but it is impossible to list these here, the best advice I have is to take a ride round the Circuit and see what is available near to your chosen spot. Park legally and safely with respect for the locals and their property and you will be fine.
2026 Southern 100 Schedule :
Please note : This is the provisional schedule and subject to change.
