In reply to smitghga34 – here are the stats from my Strava account:
St Jacques Day 1 69.0km 2,096m
Compostela Day 2 62.4km 1,240m
Compostela Day 3 72.7km 1,769m
Compostela Day 4 13.8km 331m
So we rode for 4 days, the last being easy-peasy, as you can see. About 80 percent was off road. We started from Le Puy en Velay, traditional starting point for the Compostela pilgrimage trail (beware walkers/pilgrims on the trail for the first 15k or so – a couple of us had bells on our bikes to warn them). Nearest international airport is Lyon. There are companies like ‘La Malle Postale’ that will ferry your gear and your bike back to your car at the end – I think we paid 250euros for 5 bikes and 5 blokes in a Renault van from the end point in Conquest back to Le Puy, which isn’t bad, and the driver was a cool mountainbiking dude himself, so conversation was good.
Generally there aren’t too many walkers on the trail, and if you say ‘bonjour’, slow down, and be nice they are very tolerant in my opinion. Only once did we get a bit of bad vibes from a pilgrimette/randonneuse who wasn’t into the whole VTT thing.
