Hi, Have most of you who have completed the del Norte done the long stage from Santander to Santillana del Mar? If so, how difficult was it and how long did it actually take? (I know many of you will recommend just seeing how we feel and going as far as we can/want that day. However, I'm hoping to learn from others who have done the entire stage). We will take a rest day in Santander before continuing on. Thanks so much!
