This is to some degree a sub-topic of the generic future courses thread. However, it’s sufficiently specific that I thought it justified it’s own thread.
There’s all of the tantalizing dirt roads branching off from the roads in France. Surely these aren’t to mock us, but Zwift plans to liberate them for public access. Please do so! Meanwhile there’s multiple gravel bikes for sale in the Drop Shop, but they’re all basically useless. The only sustained dirt section is the Jungle Loop, which is faster on a mountain bike.
I took a low-resolution copy of the French map (from ZwiftInsider) and sketched in some of the dirt roads already drawn on the map. In some cases I took artistic license and connected stubs. Look at the possibilities!
Here’s my map, showing just a brief attempt to draw in some routes. Of course there could be more paved routes in France as well, for example “le Midi-GPM” to complement “le Petit GPM”, but that’s a separate matter. Here I show a dirt road which serves a similar role, bypassing a larger portion of the Ventoux climb, working off what I see already available on the map. I drew in the yellow, in many cases tracing over what was originally there. Some of the original dirt which I did not trace over is visible as a darker brown.
This is version 3 of my map, after Eric was nice enough to send me a high-resolution France map. Note the road out to St Michel, which exists and is paved IRL, and was used in a Tour de France time trial.
Note the dirt which parallels the climb towards Ventoux is adjacent to the railway. The railroad enters a tunnel: the terrain is relatively rugged there. So I’m assuming some way to get from there to the paved road.
I’ve also added a proposed paved climb from the coast because… why not?
