The BMW MOA has a mileage contest every year and the rules are on their site. They messed it up a couple of years ago by introducing a bunch of different timeframes for the competition and interest and participation dropped considerably.
The TCD used to have a very informal approach: Just claim up how many miles you rode and declare it at our awards dinner. (Only BMW miles count, btw)
Get a round of applause and a plaque named after a former long distance riding member.
That’s how it’s always been done. And god help you if you didn’t attend a rally. You’d be awarded a 5 foot tall albatross trophy full of broken motorcycle toys.
It’d be great if we could come up with something that could involve more members and encourage them to ride. This was only something that very few people really were involved with.
It’s not a bad tradition, but not many people really participated in recent years.
