Hi, Lucy,
Welcome to the forum! As you search around the forum with the now much-improved search function up on the right, you'll find lots of threads about women walking alone, safety, sense of security, etc. Let me just say that as a 63 year old woman who has been walking caminos "alone" since 2000, I have never felt threatened or unsafe. And that includes many nights alone in albergues on un-traveled Caminos where I have been the only peregrina for days on end. On the Francés, it will be up to you to decide whether you want to walk alone or with others, and you´ll be amazed at how quickly your Camino family is formed. I think you will get a lot of reassurance reading the experiences of others, because there are many of us who walk alone by choice. Buen camino, Laurie
