In reply to Newbuild100:
Since I grew up close to Lindale (assume you mean the one near Grange over Sands) here's my take.
Head up the Winster valley to Bowland Bridge, then Crook, Ings, back road to Troutbeck, up to Ambleside, Clappersgate, almost to Hawkshead then across towards Coniston but follow east side of lake to Spark Bridge, Bouth, Haverthwaite, Holker, Cark, Cartmel and back to Lindale.
Not sure on the exact mileage but it will be around 60 miles and with the exception of the bit from Troutbeck to Ambleside is on back roads.
