No gps files please, best way is to tag along with a local group and respect the less than official trails
One of the big factors in the conception of the trails was to offer riders a year round guaranteed rideable trail. Back in the early 00's there was an undercurrent of ill-feeling to what was largely local riders in decent number using the trails but there was an increasing number of visitors who were turning up on the Chase failing to find many of the decent trail who then left criticising the lack of riding
There are other factors as there were a collective of interested parties involved in the concept of the trails, these were just my drivers.
One result of having the waymarked trails was to help reduce pressure on other more sensitive parts of the forest but then over the years rider numbers have increased significantly so the impact on the off-piste stuff hasn't really lessened in my view.
It's ironic now though given my comments above that the waymarked trails are now being criticised.
The pebbles are imported from other parts of the Chase, without the addition of surfacing the trails would be a mud bath in the winter and would be ruined long before they ever got down to the underlying material and even then would sit too low on the surface to ever drain properly.
At least the worst you have to put up with a puddling, and an element of grinding paste, FtD and the Monkey don't get particularly muddy (except when frozen trails start to thaw in winter)
