Hi Nellie G, I see this is your first post, Welcome. I know what you mean about how routine exercise can get boring. I found using local and National walking routes helped to spice things up a bit.
I also came across a range of books 'AA 50 Walks' that help me find those routes. The books cover routes by locality. So if you were in Yorkshire, there may be a book for that, this may also help you plan for walking routes when holidaying in the UK. Click this LINK to purchase and find out what areas are covered.
I hope this helps![]()
