Today was brutal. -10C (14F) in the morning with a 40kmph (25mph) headwind. The afternoon ride was -8C (18F), and the wind gusts had picked up to 70kmph (44mph). Snow drifts were everywhere, making the "clear" roads unrideable in places. I ended up doing 69km (43 miles) in this today, mainly just to see if I could. Now that I've done it, I don't think I want to do it again.
