Lots of KMs

Since the extra day in Burgos I've gone 67 km: 32 yesterday (to a village called Hontanas) and today I'm in Fromista, 35 km beyond Hontanas. 

My feet, legs and hips hurt after about 20km but they don't really hurt any worse  after that so the difference between walking 20km and 35km is just another 3.5-4 hours of painful feet, legs and hips rather than an increasing amount of pain over that period. Does that make sense?

Here's a selfie.
