Some altitude profile from gps:

Coldest temp I have been bicycling this season is around -30C, I did postpone one of the trips due temperature being -35C few days ago, but -10C is not very horrible.
During the night one can see so many stars at sky that it is hard to tell where Orion or even northern star is, also during the night if there is no wind, there simply is no any sound at all that one could hear, just silence, complete void of any kind of sounds, so your breathing sounds loud and it is easy to hear heart and blood running, total soundless area and no any lights, except from the stars, only thing reminding from civilization is the road.
