I've now spent over £100 on maps!! I still would benefit from help, so if anyone knows Scotland/ Cumbria/ Bristol area/s please do not hesitate to contact me.
So far the route plan is as follows:
Set out from John O'Groats on 1st July, head towards Inverness (slightly vague! Not sure if heading west first then dropping down or heading down east coast- awaiting yet MORE maps) ride along great glen way( loch mess and loch lochy) to fort William, west highland way down to Glasgow, shadow Pennine wat until it joins Pennine bridleway at Hebdon bridge, follow trail to great barrington. Along Sabrina way, Cotswolds, cheddar gorge, Somerset, Dorset, devon (dartmoor), finish along the kernow horse trail in cornwall to Land's end- the home! Simple.
