For the first few hours your legs don’t complain at all, and your mind goes quiet by itself. Your knees only start to speak up later: this stage has more descent than climbing. At around 23 kilometres it’s an average stage, but one you will feel.
After Hospital, turn right towards Dumbría and Muxía. Don’t miss that turning. There are few facilities until Dumbría, so take food and drink with you for the stretch in between. You’ll arrive in A Grixa with heavy legs and a calm mind. Go at your own pace, the Camino isn’t going anywhere.
