Today the outside temp is -6 deg and my garage temp is -1 deg, so this video seemed appropriate for my effort today. Although I have used ice tyres before I don't think I would have covered the route you did in anywhere near the time you did it in!
This is the weather when nature is trying to kill you. Very slippery and icy roads. Thin water layer in top of ice. Doing my best to keep lens clean from mist. Nice ride with ice spikes on tyres.
