The right gear makes all the difference. Proper cold stuff made the 90 minutes mostly in the dark that much more enjoyable. The stiff headphone cords was one of the few reminders that it was around 10. Too cold for slush and no need for fenders had me out on the rivet, repeats on the safer loops, the blinky keeping me safe from behind. Everything increases exponentially in the cold, the legs feel like I did double the work, the body still slightly stiff, soft touch on the handlebars, studded tire would give that confidence I lack. It all adds up nicely to proper Winter Work.
