Cycling the Camino is a great way to go...especially if you have limited time.
I would make one suggestion though...consider using a bell to announce your approach. Often, especially on downhills with an immediate uphill...the walker may be carefully negotiating the path and...whoosh...a bike makes an appearance which can be unsettling. It's even more dangerous on a blind turn.
