500 pre 1931 motorcycles are entered for the VMCC's annual Banbury Run, starting and finishing at the Heritage Motor Centre, Gaydon, Warks CV35 0BJ (12 miles north of Banbury, Next to M40 J12).
This is a very well established event, in fact, this year is it's 68th running, and is advertised as the "the largest gathering of veteran and vintage machines in the world". The bikes set off in batches of 5 at 1 minute intervals and have a route map to navigate their way around whichever route they've entered.
2015's routes were as follows and I'm guessing 2016's will be similar.
"Veterans" (pre 1915 machines) have a gentle 30+ mile route. (some of these bikes are single-speed belt-drive total-loss with stirrup brakes, so the ride can be a bit of a challenge......)
"Early Vintage" (1915 - 1924) have a 50+ mile route.
"Late Vintage" (1925 - 1930) have a 60+ mile route
This year, the bikes range from 1899 to 1930, so the oldest bike is a mere 117 years old! (and you thought your machine was getting on a bit!!)
