I biked for three weeks through temps in the 20s, with Nokian snow tires on, and I'm beat. Legs sore, perineal discomfort, fatigue. I need to remind myself that at 56, with all these layers, it's OK to slow down. You tend to mash gears in this weather, and that hurts. Still, an hour or 90 minutes going slowly in this weather is still better than a trainer. So, yeah, let's get his over with. I am leaving tomorrow for ten days in the Bay Area, where I hope to ride, but also to take some time off to recover.
