How Climate Change is Transforming Running Habits




Adapting to New Climate Realities

Danielle O'Hanley, a dedicated runner from Toronto, has become accustomed to modifying her running schedule to avoid extreme weather conditions. This summer, she faced a new challenge: wildfire smoke. The record-breaking fires across Canada, fueled by drought and high temperatures, brought a stark realization about the impact of climate change on her routine.

"I started running early in the morning to escape the intense heat, but the wildfire smoke added a new layer of difficulty," O'Hanley shared. When smoke levels are high, she opts for indoor treadmill runs to maintain her fitness without risking her health.

Run Clubs and Events Adapt

Run clubs and events have also been forced to adapt. Kirsten Fleming, executive director of Run Calgary, noted a significant shift in the industry. "When I started, event cancellations were rare. Now, it's a regular occurrence due to various climate-related issues," Fleming explained. To navigate these challenges, Run Calgary employs a meteorologist for daily weather briefings leading up to their events.

Nighttime Runs and Hydration

Midnight Runners, an international organization that coordinates nighttime runs, has noticed an increase in hot evening temperatures. "We've had to cancel runs due to air quality concerns, but we're constantly communicating with our runners to ensure their safety," said Ben Davies, an organizer for the Toronto chapter. Hydration and adjusting pace are crucial strategies for coping with the heat.

Health Considerations

Experts like Dr. Michael Brauer from the University of British Columbia emphasize the importance of monitoring air quality and adjusting running times accordingly. While exercise generally has health benefits, running in heavily polluted air can do more harm than good. Extreme heat poses additional risks, from heat exhaustion to heat stroke, particularly for older adults and young children.

The Future of Running

As climate change continues to impact weather patterns, runners and event organizers must remain vigilant and adaptable. "Don't put yourself at risk for a run," advises Fleming. "There's always tomorrow."


 Danielle O'Hanley from Toronto adjusts her running schedule to avoid extreme weather, including early morning runs to beat the heat and treadmill sessions during wildfire smoke. This adjustment reflects a broader trend among runners and running events facing increasing challenges due to climate change. Run clubs and events now frequently monitor weather conditions and cancel events for safety reasons. The article highlights the adaptations runners and organizers are making to cope with the impacts of climate change, including heat, smoke, and extreme weather.

Frequently Asked Questions (FAQs)

1. How is climate change affecting running? Climate change is causing extreme weather conditions, such as heatwaves, wildfires, and smog, making outdoor running more challenging and sometimes unsafe.

2. What adjustments are runners making? Runners are adjusting their schedules to avoid peak heat and poor air quality, using treadmills during extreme conditions, and paying more attention to weather forecasts and air quality indices.

3. How are run clubs and events responding to climate change? Run clubs and event organizers are monitoring weather conditions more closely, hiring meteorologists for forecasts, and canceling or rescheduling events to ensure participant safety.

4. What are the health risks of running in extreme weather? Running in extreme heat can lead to heat exhaustion or heat stroke, while running in wildfire smoke can cause respiratory issues. It is crucial to adjust running times, stay hydrated, and listen to your body.

5. What resources can runners use to stay safe? Runners should consult resources like Environment and Climate Change Canada's Air Quality Health Index to determine the best times to run and understand the risks associated with various weather conditions.
