What to Wear Running in 0 Degree Weather
A general guide. For your exact conditions, check your city.
Layer up: a thermal base, an insulated mid, and a wind-blocking outer, with thermal tights, a beanie over the ears, gloves, and a buff for your neck and face.
The short version
At 0°F the question stops being about comfort and starts being about skin and traction. Cover every inch of exposed skin, layer in thin, removable pieces, and be honest about whether the run belongs outside today. Short, easy loops close to home are the smart play.

Zero degrees calls for a full cold-weather system. Start with a snug merino or synthetic base, add a thermal mid layer, and finish with a wind-blocking shell on top. Fleece-lined tights, thick running socks, and mittens over thin liner gloves keep the extremities working, since mittens hold heat better than gloves. A balaclava or buff pulled over the nose and cheeks protects the skin the wind hits hardest, and a thin balm on any exposed patch adds a small barrier.
The mistakes at 0°F are about moisture and exposure. A base layer soaked with sweat turns cold fast once you slow down, so keep the effort easy and avoid stopping far from shelter. Cotton anywhere on your body is a bad idea. Cold air also stings the lungs, which a buff over the mouth softens by warming each breath slightly. Footing is the other hazard: packed snow and ice call for traction cleats, and a short route you can bail out of beats a long point-to-point.
At this temperature the wind chill matters more than the thermometer, because even a light breeze can drop the feels-like well below zero and shorten the time exposed skin can tolerate. Check it before you leave and be willing to move the run to a treadmill when it plunges. Dress so you feel cold for the first five minutes, warm up indoors with a few minutes of drills, and plan the route so the return leg is not straight into the wind.
