That looks right up my street (in some places almost literally)
Had a good look at yr map and have done most of the minor-road and bridleway sections between Bridgnorth and Cheltenham over the years, but wasn’t aware of this route! Looks like a good rough-touring/bikepacking option for the 29er, with a few good camp-spots on the way 👍🏼
Some hilly and sections near Witley, Malverns, Suckley (muddy hell in rainy weather) etc, but all good fun. Try and arrange so you happen upon the beer festival at the Talbot in Knightwick en route and you’ll get a good night’s kip 😉
Don’t bivvy on Osebury Rock though, the ‘little folk’ will come for you in the night…
