You speak to the land owner and ask for it to be designated a permissive (for cycles) path, or in the case of council owned land such as urban common, you can refer to other precedents where the land owner has classified cyclists with the same rights as walkers.
Obviously this works well im some areas but I just have a feeling if you contact some landlords in busy parts of the country it will just alert them to you and they’ll quickly get the fences going up so only walkers can access the land.
I did once contact a landowner.
There is a small ford here ->

It currently can be crossed by horse/car and there is a footpath on a small bridge next to it.
Would be a great commuting (not mtbing) route between the villages on the edge of Reading.
I suggested the footpath to the bridge should be rerouted and classified as a footpath/cycleway I also wrote that it should be down at the edge of the field so as not to disturb the horses. The land owner said not happening.
I contact the local council who said a small budget would be coming up for cycling improvements and would get back to me but never did.
what do you suggest Sandro ? I can forward you the emails.
I also started this petition.
