As temperatures drop in the winter months, many outdoor activities move indoors. However, runners still gear up and train for races year round. 

Christopher Lundstrom, a lecturer in the School of Kinesiology, shares tips on how to approach running in cold temperatures.

Q: Is it safe to run in cold weather?

For the vast majority of runners, heading out in the cold is quite safe when done with proper clothing. The main concerns for the typical runner are hypothermia and frostbite. Hypothermia occurs when the body temperature drops, which can happen in cold temperatures as well as milder temps when it is wet and/or windy. 

The good news is that running and other forms of exercise naturally produce heat, and allow you to maintain your body temperature wearing lighter clothing than you would be able to get away with if you were not exercising. 

Frostbite occurs when the skin freezes, typically due to leaving skin exposed in very cold weather. There is also an increase in cardiovascular demand in cold temperatures, which is potentially concerning for anyone with heart issues. 

Similarly, those with asthma or other pulmonary issues may need to consult with a medical professional prior to exercise. But the good news is that if you keep your core temperature up and protect your skin, most people can comfortably and safely run in cold weather. 

Q: How should runners prepare for low temperatures?

The first step is to check the weather conditions, including temperature, wind and precipitation. Understanding what conditions you are likely to encounter during your run allows you to dress appropriately and potentially choose an optimal route. 

Dressing in layers is a basic, yet very important suggestion for cold weather exercise. A breathable base layer and a weather-resistant outer layer are a good start. Gloves or mittens, and a warm hat that covers your ears will keep those extremities protected from the elements. On particularly cold or windy days, a skin barrier product can provide protection for any skin that remains exposed, such as cheeks and nose, though a winter face mask is also a good option. 

In terms of route selection, if it is icy, avoid high traffic areas, or choose a route where the surface has been cleared. If it is windy, you may want to run a course that goes out into the wind, and then finishes with the wind at your back. 

Q: Do runners need to adjust warm ups and cool downs in the winter season?

The main thing to pay attention to when structuring your workout is avoiding extended periods of standing around out in the elements. If you typically do some mobility or flexibility exercise before, or any core or other auxiliary exercises after your run, do all of that indoors if possible. If you don’t have that option, wear extra layers for your warmup and toss whatever you don’t need aside immediately before you start your run. After your run, get into dry clothes as soon as you can. Just a few minutes of standing around in the cold in sweaty clothes can cause your body temperature to plummet. If you are doing some type of an interval workout or other workout that includes breaks during the run, be sure to keep moving enough to keep your body temperature up.

Q: How can someone avoid slipping or falling? Any tips for bouncing back from an injury?

When the footing is icy or slippery, use caution in terms of where you are stepping, and slow down and shorten your stride as needed. Likewise, be cautious around hills. You have to push a little harder to go up, which can lead to more slipping, and going down hills tends to cause an increase in speed, which makes you more likely to fall. 

If you do a lot of running on ice and snow, ice traction cleats are a worthwhile investment. These can be slid over your running shoes for the runs when you need them, and easily removed when the roads are clear. If you do strain a muscle due to slipping, it’s better to take a few days off or cross train right away to allow it to heal, rather than continuing to run on icy roads that may exacerbate your strain.  

Q: What additional resources might be helpful to consider?

Refer to current weather conditions, taking into account both temperature and windchill. Don’t forget to account for your own speed of movement, which adds to the effective wind speed. In other words, if you are running 6 mph into a 10 mph wind, the effect is the same as a 16 mph wind standing still.
