TAB to Bowland

TAB is my newly discovered word. I'd heard it several times over recent years, but only in the last few days discovered its derivation. It stands for Tactical Advance to Battle, or in this instance, Tactical Advance to Bowland.
We (as in wfdbwgua) are planning a TAB on Saturday 26th January, commencing from GR SD 632 513, near Dunsop Bridge, at a time yet to be agreed.
We will proceed up the Langden Valley to Langden Castle (Google it). thence to Fairsnape Fell:-

Note:- it may not be this sunny on the 26th and the paint on the trig pillar might have faded.

From there we will turn south and then east to return to our start point. Total distance about 10.5 miles, starting on track and then rough fell. Forecast is dry, but cloudy.
I can forward a map to anyone who is interested.
