Pack weight sounds good. Mine was 15 lbs. (plus food at water)
I did meet one guy (Paul - you know who you are) that had a pack that was probably 5-6 lbs!
Couldn't keep up with him! He was fast.........
But remember you'll be carrying a lot of water on some stages. Often all your water for the day. I carried 2 litres most days, 1.5 some, 3 others. Depending on distance, heat and what was along the way. Unless passing through a 'larger' village or town, assume no water or food available along the way. I always checked ahead 2 days on google maps looking for shops, cafes etc and checking opening times. (which are sometimes wrong)
To show how different we all are, Paul probably carried 1 litre for the day! But he would arrive 2 hours ahead of me.
I started 25 March last year and it was perfect re weather. Just check the dates of Semana Santa. Accommodation gets heavily booked.
My approach was different. (most go West on the Sanabres)
I went North to Astorga which was a really great section, then West on the Frances to Ponferrada, then on the Invierno to Santiago. It was great.
I'm keeping the Sanabres for another time.
