The temperature was perhaps 15F with a stiff headwind going out.
I was comfortable riding out using Bar Mitts with wool mittens inside, along with my usual assortment of gear. I have started wearing a waterproof shell over my softshell jacket for additional wind protection on very cold days.
Once I stopped and hucked the tree, I decided to take the long way home through the country to see the scenery. That plan worked pretty wheel until about mile 12, when I found myself at the bottom of a valley at the Abington/Salisbury intersection with a dying battery and about 120 lbs of bike to get home. Ah well, I succeeded at getting a good workout on a day I might have otherwise stayed inside.
