Electric bicycles are not allowed.

Only mountain bikes with wheels 26, 27.5 or 29 inches in diameter will be allowed, and also cyclo-cross or gravel bikes with off-road tyres.

All the tubes (frame, handlebars, connections, etc.) on the bicycle must be covered.

It is recommended that participants should carry with them all the spares necessary to repair the bike.

It is compulsory to carry a white light at the front of the bike which should be switched on from dusk to dawn. A red light should be carried on the rear and this should be kept on during the whole route.

Any bikes that in the opinion of the organising committee do not comply with the necessary safety elements for the event will not be authorised to start the route.
