Know where the snow is. Trails on north-facing slopes tend to stay snowy and icy for most of the winter; snow on flat and south-facing slopes tends to melt away quickly.
Step2
Avoid running in the late afternoon when the daylight hours are limited and you risk being caught out in the dark.
Step3
Choose well-defined trails and only run on trails that you're familiar with. Snow tends to make all trails look the same.
Step4
Bring appropriate clothing (including trail-running shoes, warm gloves and a hat) and be prepared for poor weather conditions. Wear layers and adjust your level of insulation according to how you feel.
Step5
Keep your eyes peeled for ice patches. Trails that see a lot of traffic while the snow is on the ground often form a slick layer of ice as the temperature drops.
Step6
Beware of objects such as rocks and logs hidden beneath the snow. Run in control and at an easy pace to avoid spraining an ankle on an obstacle.
Step7
Be especially careful when running on steep hills. Snow can turn an otherwise easy ascent into an extremely slippery nightmare.
Step8
Watch for covered stream crossings or other water crossings to avoid falling through thin ice.
Tips & Warnings
Never wear cotton. Once cotton is wet, it stays wet - and you stay cold.
In deep snow, wear lightweight snowshoes designed for running.
Running in snow can be hard work. Be sure to compensate by drinking extra water and carrying enough food to keep your energy level high.
