What does BPF mean on the description of controls panoramix?
As far as I can tell (thank you Mr Google), it's Brevet des Provinces Françaises - more detail at
http://www.ffct.org/index.php?id=365.
Six spots in each French departement, picked to be of interest to tourists for their historic, aesthetic or other appeal, and grouped by the historic provinces of France. Get a stamp from a local business (or a receipt, or a photo of your bike with the town sign or a distinctive local feature) on your brevet card, get 'em validated, and eventually you'll finish.
With a mere 534 places to visit, what are we waiting for? (Oh, and because it's supposed to encourage a tourist's enjoyment of the place - especially views or history I guess - night-time controls will not be validated. There is a simpler version, the Brevet de cyclotourisme national, where you only need one stamp per departement.)
