I don't know what I was thinking this morning. I see -18C with a 20km/h headwind and decide I can wear a light merino layer under my jacket instead of a heavy wool sweater on top. Past the half-way point I decide I really need another layer, so I stop and pull out my jogging windbreaker. Despite it being breathable, I was pretty soggy by the time I got to university.

-6C with a 30km/h tailwind for the ride home, should be fast and warm. Rest of the week is going to be toasty compared to last week.
