Well, it seems that all of the extra walking has paid off: I'm making good time and should be in Santiago before too long, just over a week now. It's exciting to look at a map of Spain and to trace the route. Initially it felt daunting. Each day brought new blisters, but now each day is 20-30km closer to my destination.
It's so nice to have afternoons off and be walking only 4-6 hours a day, rather than 8 or more, as now the longest days are behind me. There's surprisingly a lot to be done in the evenings: mostly it's just washing (I only brought two sets of clothes) and also some shopping so I don't have to eat out every meal. Life on the road has it's own rhythms, but still each day on the road creates work for that night.
