The route will be as follows : -
Melmerby to 11's at Brough Village Store via Appleby and Bleatarn ( avoiding dangerous A66 crossing near Warcop ) = 26 miles
Brough to Middleton in Teesdale = 14 miles
Middleton to Melmerby via Alston = 33 miles
Total distance plotted as 73 miles and ascent plotted pessimistically as 6400 ft.
Lets hope the weather is kind to us.
