This is a photo from two years ago, i stood there for a good minute wondering how the hell and why this weird cycle path was there. It is in southern France, on the climb to Col d’Ecre, bit north of Nice.
Take a guess, i finally fully understand.
Hmm, something like a chip timing station so you can time your climb?
Presumably there would be similar ones at the bottom and top also, and perhaps at other points along the way.
