How come when walking the 774 kilometers from SJPP to Santiago I rarely experienced sore muscles and now that I’ve returned my thighs ache and I have a touch of sciatica? We are walking much less now. In bad weather, like the hurricane on Tuesday we walked 0.0 kms. Today we walked about 10.4 kms or about half a Camino day’s walk (without packs, rocks on the trail or ups and downs). The days in between Tuesday and today we walked less than today but more than Tuesday. Yet I’ve been achy for the past few days. Endorphine withdrawal? Delayed recovery of pain receptors? Any ideas?
