Burgos to Santiago

Hi and welcome to the forum @Jdonnellan ,

The distance from Burgos to Santiago is ~500km, only you know if you are used to bike ~80km per day. Also, end of October there is a good chance of rain aka mud meaning you will be slowed down by this or have to take the, sometimes very busy, roads. On the other hand you might be lucky and have wonderful sunny and dry weather. Buen Camino, SY

PS Also keep an eye on http://www.aprinca.com/alberguesinvierno/ to see which albergues are open.

I am in agreement with SY - Burgos to Santiago is a "long way" even for Spain. If your intent is to try to follow the walkers Camino path then 80 km a day is in some places going to be difficult. That said it is possible to follow the walkers from Burgos to Rabanal, after that I, for the majority, stuck to the roads - often the Camino was 10 or 20 metres off to the left or right. You should factor in that you have two significant hill/mountain climbs - Astorga/Rabanal/Cruz de Ferro (and from here a really "interesting" descent) and again from Ruitelan/Herrerias/Laguna de Castilla/O'Cebreiro - and here you will have to follow the sealed road - the walkers track totally unsuitable for bikes. On other aside - doing 75 km per day you are not really going to get that Camino feeling/experience (imho) - I rode at half your predicted distance and still missed a lot hence I am going back to walk it next May. Best wishes.
