We left Sao Joao bright and early in a clear, hot-day's dawn. We saw an interesting little chapel on the way out.
This was before we got to the top of the long uphill climb through town and discovered what the route marks are apparently aimed at: the widest smooth sidewalk in Portugal.
We walked up and down, even on some original Roman road surface, and ended up in the Albergue de la parochial de San Salvador de Grijo. It was a short 18-20 km walk and didn't get toasty hot until I was washing our socks out. By the way, does anyone know how to get adhesive tape glue out of socks? The tape glue just melts through the tape fabric while we walk.
And with that question I think I'll close this and take a nap.
