Just noticed that after Knighton you are taking the official route to Weobley. Despite being shorter, these lanes are really grim riding. Very potholey, gravely and often very muddy making them quite slow going. You'll be better off pressing on a Brampton Bryan and taking the A roads south to Weobley from there. Quite a few other riders will be doing the same. It adds about 1km but has a fraction less climbing and will definitely be quicker and take less effort.
