The old start line grandstands just on the outskirts of Reims, might be a bit of a road trip cliché these days, and the newly painted concrete has robbed the crumbling buildings of some of their bygone-era mystique, but the old circuit is still worth a look if you're ever passing by that way.
To start with, the circuit, which was an F1 venue until 1966 and held sports car races up until 1972, is barely a stone's throw away from the autoroute as you skim past Reims.
It's also a pretty evocative place, although the rush-hour traffic on the road to Gueux does spoil your reveries of Lotuses and BRMs chasing one another down the road...
