Today felt like a long day. The first part, leaving Portugalete involved riding the escalators up the hill. Then it was a lot of combined bike lanes and pedestrian lanes, so no traffic, but largely along side of freeways and all pavement. After about 3 hrs of solid walking stopped in Las Arenas for a quick snack and then continued on. A beautiful beach which in spite of mid 60s temperatures was being enjoyed by many people. A pretty big set of stairs led up to a coastal path and there were lots of mining remnants from a previous era. At some point I reached a split between the coastal route and the inland route and as I was pausing a number of people were waiting for a bus to Castro Urdiales. At this point I think I had walked about 20km and my feet were definitely sore, as I was debating whether to continue, the bus showed up, so hopped on and 15 minutes later was at my hotel! Since tomorrow is scheduled to be much longer than I would like I decided this was a good option, and it gave me a little time to explore the lovely beach side town of Castro Urdiales. See photos below. Step counter reading 34,306 for the day!
