It is for anyone who is able to walk.
A couple or family could do it together. Children as well as adults should enjoy acquiring the stamps and stickers and getting their plaques and Bibles in Eyam. Youth and school groups could do it. Church groups would enjoy it. Any walking group might appreciate a good walk with an added pilgrimage dimension. Even pensioners with slightly dodgy knees will manage it. Or you could get away from it all and quietly walk the pilgrimage route all by yourself.
