Navarette to Burgos 78 miles

Left Navarette on my very good road which continued for another 10 k until I reached the end of the current motorway development at which point heavy  traffic rejoins the road, making for an unpleasant cavalcade of lorries. Had to get away from this!  The next town   (Domingo de San ........?)  at 15k from Navarette was a good place to stop for  a coffee and croissant and to buy a map.  Left  here and using smaller hill roads continued on my way- a longer route but so much nicer! Passed thru' hill towns with their little churches and heard cuckoos. Caught in a heavy rainstorm. Met up with some other travellers absolutely plastered in this gypsum like mud. Returned to main route to enter Burgos and was shown way to refuge next to cathedral by locals.Unfortunately, I must have lost my Pilgrim's Passport somewhere today but they let me stay here anyway-I have had to buy another one. Really nice place-quite modern inside, but only 3 Euros!
