If it’s Blackburn, Lancashire, then you’ve got quite a bit to go at as above. I’d probably go and park opposite Roddlesworth near the Royal Arms in Tockholes.
Head up to the Tower, take in some moorland tracks, pick your descent down (the long diagonal front is the best) then head across into Roddlesworth woods, again pick your track to cross over to Abbey Village (there’s some good stuff if you know where to look) head up onto Great Hill. Then down either White Coppice or one of the nice trails in Brinscall woods, along the goyt and over to Healey Nab for a lap or two. Then back you go to The Royal.
You could make the loop a longer (add in Rivi) or shorter if you wished too.
Give me a shout if you want any pointers!
