As above, top of south loop, through trees to sleet how and down to Braithwaite-steps of doom challenge at the bottom, (sensitively please, easy to slither out of control on muddy slippery grass descent on a popular walking route).
There are 2 BWs down, one off the main whinlatter road which isn’t worth bothering, but the one from NY212247 down comb beck is great. You can pick a cheeky way along to `Braithwaite from the end of that one, along the track then FP above Ladstock and Lanefoot farm back to Braithwaite to avoid the road. I do the first section of North red, then turn right down the forest road to the start, well signed.
There is also the FP to Powter How, but you need to be better than me to enjoy the top section of that, and there’s an awkward scramble across a slimy slab that is tricky carrying a bike!
