Biking the Portugues Coastal Route September 2015

[Joyus]

I'm so excited! I am biking this route with my mother, aunt and a friend. We have chosen to bike the coastal route for various reasons, but I would like first hand information/advice! Has anyone done this lately..in the last year perhaps? I am looking for any advice, tips, etc. I am 49 years old and fit, my mom is a fit and lively 72 year old, her sister is the same at 66 and friend at 65. Our biggest concern at this point is safety along the route as far as traffic is concerned....any parts that are on busy streets,etc? (I have purchased the John Brierley guide) Thanks in advance for any info!!
