It might be better not to ask us. We always walk everything, because we think that is part of the Camino: to take the journey as it comes, with its beautiful and less beautiful sides.
Of course sometimes we ask ourselves: Why are we doing this? But the choice to walk the whole way also leads to the most beautiful surprises. And it brings a certain peace: "This is what I do. I am not always wondering if this is good or whether I should somehow do it differently."
So, if you don't have the time to walk or bike all the way to Santiago, maybe you can do it in two stages instead? Or try to arrange more time off? (We have heard some wonderful stories about this) Or go next year, and save extra vacation days in the meantime?
