As someone who works in the Public Sector and Countryside its always hard to put up with the 'oh no they've gone and ruined another trail' complaints AFTER the event.
I did write into the Access debate but it never got mentioned so here is my advice:
The Public Sector does what the Public asks them to do. If the public say a section of FP/BW is impassable then the Local Authority will go out and do something about it.
Singletrack have met CMBC staff about which trails they really like in there current state. They have marked them on a CMBC map so if any complaints come in about the state of the route CMBC can now decide whether to leave the route as it is or to carry out work. IF they carry out the work they know to contact MTB groups.
Did anyone here write to Cumbria to say which routes they like, have they met with the PROW dept and marked on a map the routes that they like?
If and when the LA do the work it will be to the standard specification for Bridleways which is 3m wide with a camber or crossfall and no obstructions.
Looking at the picture of Walna Scar it looks like some kind of Sub soil track with a kind of softcore IMBA spec. It is hard to use the full IMBA spec for BW (we've used it on the new PBW section over the moors down to Thursden and Tony has used it to link Lee and Cragg Quarry) as horses struggle to see the rolling grade dips and this can cause them to trip/stumble. We have had complaints about them.
So to summarize, please dont complain AFTER the event. Next time you enjoy a ride over an eroded section of trail. Mark it on a map and go to the PROW officer and say 'this bit is fantastic', 'please dont do any work to it' and if you do please can you consult my local MTB club/IMBA/CTC first.
If you dont someone will complain its too rocky and before you know it, its 3m wide with no obstructions.
