Who are ACP and LRM and why are we associated with them?

Audax Club Parisien (ACP)

As you’ll have read in the History of Paris-Brest-Paris, ACP is over a hundred years old, being founded in 1904. It is, by a long way, the “senior” body in our sport, when you compare it with Audax UK which was founded in 1976.

Audax UK’s event regulations are very much based on those of ACP which can be found here (and in the original French here).

ACP also “homologates” (validates is probably a more usual English word) all the events, worldwide, which are classed as BRM (Brevets de Randonneur Mondiaux).   These events are at set nominal distances and ACP defines the maximum time for each length of event:

  • 200km: 13 hrs 30 min
  • 300km: 20:00 hrs
  • 400km: 27:00 hrs
  • 600km: 40:00 hrs
  • 1000km: 75:00 hrs

If you look in the AUK results tables, you will see that, for “BRM” events, there is (after a short delay) an ACP Brevet Number. This is a unique number allocated by ACP, who have kept a record of all successful rides under these regulations, at first in handwritten ledgers and later on computer.

The documents linked below are the agreement between ACP and their appointed representative in the UK identifying Audax UK as the body appointed to organise BRM (and by extension, LRM) validated events in the UK.

Les Randonneurs Mondiaux (LRM)

In 1983, after the 10th Paris-Brest-Paris randonnée, a world-wide organisation named Les Randonneurs Mondiaux (LRM) was created. 

Audax Club Parisien appoints national representatives to administer the BRM regulations in their own countries. These representatives automatically become members of LRM, a division of ACP comprised of them and representatives of the ACP executive. LRM has the sanctioning authority for events of 1200 km and longer, with the exception of Paris-Brest-Paris. These are labelled RM in the AUK calendar.

Audax UK riders riding BRM and RM events in other countries may apply to the Recorder to have their ride added to the AUK member records.

Both ACP and LRM’s websites have calendars of all their sanctioned events worldwide to facilitate riding in another country. Indeed there is a special LRM award to promote this. See the ISR page.



Audax UK is affiliated to Cycling UK, Union Audax Francais, and Cycling Time Trials.
