Castle Combe Race Circuit, Castle Combe, Upper Castle Combe, Chippenham SN14 7EY

Parking

There is plenty parking available, and the car park will be clearly signposted from all directions when approaching the venue.

Additional Information:

Timing chips will be collected from the registration desk on race day. Timing chips must be fitted securely to the left ankle.

Competitors are responsible for counting their own bike laps – plan how to do this to avoid mistakes on the day. The timing system will produce results for each lap and anyone not completing the required distance will be marked as a DNF.

Start System & Warming Up

The start system is relatively relaxed with riders given a 10-minute slot in which they can start. Riders can choose to do a half-lap or 1.5 lap warm-up before joining the start queue in the chicane before the start flags and start line. Please stay off the racing lien when warming up or cooling down

Live Results

Live results including lap splits and leaderboard will be available to view on smartphones at DB Max Sports Timing (dbmaxresults.co.uk).

Please remember to give back your chip at the finish as any not received will be billed at £70.

We cannot wait to welcome you back for another year of exhilarating TT racing, so jump off those smart trainers, dust off your bikes and get set to make a flying start to 2026!


Competitor's Machine

Make sure your machine is well-built, equipped, and properly maintained for safe road riding under all conditions. Adjust the riding position to ensure good forward vision while in a competitive stance.

Where should I place my brake levers?

- Secure the brake levers to the handlebars, allowing the competitor to easily apply both brakes while holding the handlebars at their widest point.

- For tricycles and tandem tricycles, two brakes can operate on the front wheel, but otherwise, the braking systems must function independently on both the front and rear wheels.

Can I ride a fixed wheel bicycle?

- Yes, you can. A fixed wheel should have a left-hand threaded locking device securing the fixed sprocket. Tricycles with a fixed wheel should also have a suitable locking device or an integral system as part of the design. Machines with a fixed wheel require only a brake on the front wheel(s).

Can I use clip-on tri bars on my road bike?

- Yes, you can. Machines fitted with triathlon handlebars or similar designs that have forearm supports, or Spinaci type handlebars without forearm supports, may be used as long as the rider adopts a safe position.

What type of tyres do I need?

- Simply put, tyres should be in good condition, and tubular tyres should be securely attached to the rims.

Can I use disc wheels?

- Deep section rims, tri-spoke wheels, and similar designs are allowed. The front wheel must have at least 45% of the surface area open.

- Disc wheels or spoked wheels with covers may only be used on the rear of the machine.

Can I ride an electric bike?

- Electric bikes are not permitted.

Can I ride in the "Puppy Paws" position on my road bike?

- No, riders are not allowed to ride in the "Puppy Paws" position or simulate a TriBar position by resting their forearms on the handlebars.

What are the criteria for a road bike classification?

- Road bikes can have drop or straight handlebars, but no tri-bars, clip-on bars, or Spinaci bars are allowed.

- Disc wheels are not permitted, and both front and rear wheels must have at least 12 spokes each.

- The maximum rim depth allowed is 90mm.

Protective Helmets

What type of helmet do I need?

- All competitors must wear a helmet that is properly affixed and made of hard/soft shell construction.

- Helmets should conform to recognized standards such as SNELL B95, ANSI Z90.4, AUS/NZS 2063:96, DIN 33-954, CPSC, or EN 1078.

- It is the rider's responsibility to select a helmet that offers protection against head injury without restricting vision or hearing.

- Ensure that the helmet is properly fitted, undamaged, and in good condition.

- Note: Damaged helmets may not provide the same level of protection, and DB Max does not guarantee the adequacy of any specific standard or brand of helmet.

And Finally

The DB Max event team look forward to welcoming you to Castle Combe on race day.
