I'm starting the Camino Frances around March 20 from Saint-Jean-Pied-de-Port and wondering whether anyone has hiked the camino around that time of year and can provide feedback on the very first stage to Resconvalles. I very much would prefer to take the higher mountain route vs. the valley route that includes a lot of road walking but I'm finding it difficult to get good information on the likelihood that this will be possible in late March. I am reading that the mountain route is discouraged in "winter" but from what I see of the temperature averages in the area by late March, it is firmly early Spring by then. I am unsure if the mountains hold snow pack or if the main issue is just potentially poor weather on the day of hiking the first stage. Obviously no one can know what the specific weather will be, but I'm curious about general conditions that time of year.
Also, I'm trying to figure out how many days are most likely for my hiking style and pace. I have the Brierly book which divides the Camino Frances into 33 stages but that implies daily mileage of well under 15 mpd. On the PCT in southern CA, I regularly hiked 25 mile days and I typically hike 20 mile days in the High Sierra. I thru hiked the Colorado Trail in 28 days including four zeros if I recall correctly - so 24 hiking days or ~21 mpd. I can't see myself hiking only 15 mpd on the Camino which looks to be much easier walking. I've penciled in 20 mpd on average which puts me at Santiago with 24 days of hiking (I don't plan many if any zeros). Then I would have a few days to hike to Finnistere and/or Muxia. I have a return flight from Europe that gives me 42 days total in Europe so I have a lot of extra time built in if I finish early and was even thinking of hiking part of the Portuguese camino (in reverse) from Santiago if time permits.
Finally, from everything I've read, carrying camping gear is more trouble than its worth and I figure the hostels won't be full in late March - mid April - is this a good assumption? I'll be traveling super light if that's the case. I have some experience with this style of hiking from my trip to the Alps in 2015 except I think the Camino is a lot easier walking than anything in the Alps.
Thanks for any feedback.
