I cycled the camino first 2 weeks of october last year. The weather was exceptionally good for the time of the year. Yet, in the morning, it was ice cold. Bring both full cycling gloves (morning), and fingerless gloves (day). Wear many layers, which you discard one per one as the day progresses. I only had some rain leaving SJPP (pretty crappy to drive up the napoleon route in the mud), and the day I arrived in Santiago (queued for the compostela absolutely soaked). Most pilgrims wake up around 7AM, and I got on the route together with them. Bring a good headlight (like a petzl), and a good bikelight (like a Knog Blinder). First hour of the day you will probably ride in the dark. Keep in mind that the walkers can be pretty ignorant about walking in the dark: all over the road, dark clothes, no light, no reflectors. I've had a couple of near misses. I drove every day until 4PM, exceptionally until 5PM, and made an average of 80KM/day, which brought me from SJPP to Santiago in 10 days. Driving through the fields in the morning and seeing the sun come up bright orange is a mighty sight !!!
