I wrote some of those Trail Guides. At one point (probably 6-ish years ago), they did actually upload the magazine routes to there and I was in discussions with them to do various trail centres.
Then I got another job so didn’t have time and I’m not sure what happened with the idea in general.
Having readers upload their own rides is a total pain. You end up with wildly varying standards of route, writing style and photography plus you also have to check everything to make sure it’s all legal tracks. Easier to just employ 1 or 2 people specifically for it and pay them on a per-article basis.
I guess with the forum, Strava, other magazines etc, its so easy to find routes and riding mates that it’s simply not economical to run your own dedicated Route Guides team. No idea what the page view figures are like for that section…
