Started from the Sé do Porto and walked as far as Labruge on the Sendo Litoral route for a total of ~24km. The route goes along the coast and is a mix of sidewalk and boardwalk. It was foggy throughout the morning and then cleared up in the afternoon but stayed cool all day. The coast was beautiful.

My feet hurt. I'm going to try to do a similar mileage tomorrow and hope I acclimate to walking
