I'm with Dave for the most part though I might go as high as 15%. My
last long ride in the cold (135 km over 12 hours in -5 C weather but
with a good 3 hour layover at midpoint)did not appear to make me much
hungerier than a similar ride in summer time would. My problem was
remembering to keep drinking lots of fluids. It is very easy to
dehydrate when riding in cold weather.
