Your legs will barely notice this day, but your head will. It’s flat, it goes straight ahead and it takes a long time. Along the Canal de Castilla the kilometres slip away in an almost meditative rhythm. Almost, because around 30 kilometres is still a long way: a good 7 hours on your feet.
There are facilities only in Grijota and Amayuelas. So bring your own food and drink for the stretches in between. In Amayuelas de Abajo there is currently nowhere to sleep, because the albergue is closed. Arrange transport back to Palencia in advance, or ask there about the current situation. That way you won’t have to worry about anything along the way. Start gently, there’s a long way to go.
