I feel some sympathy for the people in charge of managing these routes when confronted by mountain bikers.
They get moaned at because a trail is a lumpy unrideable mess, so they put down a lovely smooth gravel path. Then they get moaned at because it’s too easy. They must sometimes think we’re being deliberately difficult, and as a user group we can be a little bit “goldilocks”.
It’s too difficult, it’s too easy, it’s too lumpy, it’s too smooth, as a user group we can encompass opinions ranging from “trail centers are too smooth”, to outrage that people have been braking and leaving bumps!
I wouldn’t like to try and keep us happy, we’re a bunch of asshats. (Not me, of course, but the rest of you. 😉 )
And let’s not forget, they don’t only cater to us, they have to cater to at least some access for EVERYONE, right down to the unsteady on their feet or in a wheelchair. Someone wheeling Granny to the viewpoint doesn’t relish the challenge of slippery roots and rock drop offs.
