The Rules


Authenticity is vital to Eroica Britannia. By following a few rules, every rider can contribute.

We have thousands of riders taking part in The Great British Adventure and everyone contributes to the atmosphere and ethos of the event. So we do require you to check out the pre-1987 rules.

The rules below are in place for a reason. The authenticity of the event is crucial to its success. While we do make exceptions we ask you to come on the journey with us. Make the effort and play your part.

1. Pre-1987 road racing bikes built both with gears and without gears are the only types of bicycle permitted for the 100-mile route. Modern carbon racing bikes are strictly forbidden.

2. For the 25-mile and 60-mile route reproduction bikes will only be permitted if they have a vintage look and characteristic, assembled using vintage components or replicated parts similar to the original. Strictly no mountain bikes or modern racing bikes.

3. Specific authentic bikes such as Pashley Guvnors, Speed 5s, Moultons and Bromptons can enter the 25-mile and 60-mile routes. These bikes are not encouraged for the 100-mile route. Other bikes such as military, postman and delivery bikes are allowed for the 25- and 60-mile routes.

4. Gear shifters should be on the downtube with the exception of Sturmey Archer-style gearing. Modern day integrated gear shifting within the brake levers is not allowed.

5. Pedals should have toe clips and straps. Quick release pedals are not permitted. While training shoes are not banned they are not in keeping with the ethos of the event.

6. Brake cables must pass outside the handlebars but other cables can pass inside the frame.

7. Both tubular and clinchers with inner tubes are allowed.

8. Participants must be dressed in vintage or era-specific clothing. Lycra and modern-style clothing is not permitted. Make the effort, you'll feel better for it!

9. Helmets are advisable but not compulsory. Vintage-style helmets are available to combine safety with a look in keeping with the event.
