Lisbon to Santiago in 19 days?

Hi Rich
In 2010 we took 23 days to walk from Lisbon to Santiago without a rest day(my Canadian buddy was a slavedriver). Lisbon is a beautiful city and we had 2 nights there prior to starting. Porto would also be a great stopover city. We took a bus from Sao Joao to Porto in order to have a full day to see the sights, not forgetting to sample some Port! Coimbra impressed me also. We did not go via Fatima.
There are a few industrial areas to walk through but not sure about buses.We used Laurie's guide so she would be able to help you more.
It was incredibly hot from 1st September for first week or two.( seemingly it is not usually so hot ). We managed to refill our water bottles at cafes,shops or fountains up to Porto and then no problems from there as there were many fountains.
I must admit the first section was hard but looking back it was a great adventure and I would do it again although at a cooler time of year. Hope this helps.
Bom caminho
Heather

Rich, I am a purist and have twice walked the Camino Frances from St Jean. Your project is just possible however please ask yourself why you are doing this? I for one cannot race through the stages, adding more and more kilometerage combining stages and busing through the unpleasant bits. The Camino grants one freedom, allows intriguing personal encounters, and may influence the walker much like meditation or yoga...if you will allow it to come in. Running about, "allowing" half a day to visit beautiful places, and speeding recklessly by others all in order to maintain a time table or to receive the documentation of a tried and true Pilgrim marathon runner should not be a consideration. I would do half and permit yourself to benefit from the Camino, you may "conquer" the Way but it is an empty victory if you have not been able to reflect, to internalize, and to confront yourself, not the physicality, but your true inner self, without which this is no accomplishment at all.
