I sometimes wonder about this. How many people do actually go and do these routes under their own steam? Some, obviously. Freeridenick being one of them. I don’t think there are many others though. A dozen? 20?
As an example (1) I blogged one of my favourite routes on a weekly basis from Morzine on http://www.ridemorzine.org/, gpx files, videos, in fact it became a bit of a standing joke this summer. “Where've you been today? Samoens?” Yes, I like it.
The Singletrack Crew even rode it with their guide Lionel (now he IS a pro) and followed it up with a video on the front page of this website.
Now Morzine is one the most popular biker destinations in the Alps, there are even a couple of guide books, both of which feature this route (the Bourgeoisie descent to Samoëns). I never saw another rider on the route all year. Hardly saw any tracks. This route is accessed by lift and the map reading is easy (it's signposted!).
Makes me wonder.
Example 2. Last year we rode the TMB at the same time of year as mid-September. Now this route is well know and is run commercially in both directions by any number of companies. There was one other group on the route. We never saw them but we did follow their tracks most of the way. I wondered who these guys were, 3 months later I met them. This year on the Chamonix / Zermatt we followed two bike tracks, we bumped into the riders this time. It was the same bloke as the year before.
We are a small community, there are a lot of tracks out there.
