Some of my mates did a great ride on the weekend. I know it included one track that mountain biking isn’t allowed on.
My attitude has changed a lot over time but, if I’m honest, I have to admit that I used to be the one who led the charge when exploring new tracks,and I didn’t care if it was legal or otherwise. And before you get too outraged please consider that I live in Tasmania which is three times the size of Wales with the same population as Bristol. The biggest maintenance issue with most of our tracks is that they aren’t used enough and get over grown. I have had landowners ask me to ride on their land to and help keep their tracks clear.
