Maybe break it up a bit as others have suggested, particularly if you have access to a car. One day you could walk to the shops and back. If you want a longer 'green' walk, and prefer to be inconspicuous when you walk, perhaps you could visit a garden centre, a local beauty spot, or NT or RHS property, where everyone is a visitor, if you have one nearby. Also, if it's bad weather, how about visiting a shopping mall - you may have a large one nearby if you're near the Peak District. You could walk the full length and back again. We've just visited our local one and it's one way at the moment and we felt quite safe, though it can be a bit hard on the feet and maybe the purse! You could ask your daughter if she wants to visit any of the above with you if you want company and she might not go striding out so much if she has distractions. Intersperse with occasional gardening, if that's an option, or a day out now and then to the coast, or maybe something you enjoy in the open air such as horse racing (beginning to open again now). There are lots of options without dogs but I do like being on my own sometimes.
