Audax Club Parisien (ACP) has changed the Super Randonneur Award so that it is achieved by riding an ACP 200k, 300k, 400k, and 600k brevet in a given calendar year (January 1 - December 31). Formerly the ACP used their fiscal year (11/1 - 10/31).
A note about ACP brevets calendared for November and December: the ACP adds these to their calendar in the fall of that year. So you may not see them on your region's calendar until that time of year. But once added, you can use them towards your SR award for that year.
