Organisers are reminded that all riders must sign on at all ACU permitted events on the official ACU signing on paperwork that is provided to organisers at the start of each season. The paperwork is updated each year, and it is important that the correct version of the documentation is used. This also applies to all riders who enter an event through the online entry system, this does not negate the requirement for everyone to sign on at the event on the official paperwork. Thanks for your understanding and co-operation in this matter.
