The 100th anniversary badge was given out to randonneurs who completed a 200k on the date of the anniversary of Audax Parisian in 2021. The Davis Bike Club organized their brevet as a vintage bike event.
I was underwhelmed by the completion badge which was barely larger than a thumb. It then dawned on me that it would make a nice buckle decoration. Cold set a curve in it to match a buckle blank, a little epoxy, and Bob’s your uncle.
If you look closely, you can see one cyclist to the left of the French sporting rooster and two to the right.
