Climate Change May End Long Distance Running

The world of long-distance running is facing a growing threat, one that’s not just about training and endurance, but about battling the consequences of Climate change. Extreme weather conditions, ranging from scorching heatwaves to devastating floods, have forced marathons and long-distance races to grapple with cancellations, postponements, and health concerns for participants. As climate change intensifies, these challenges are likely to become more frequent and severe.

In recent years, marathons and long-distance races across the globe have had to face unprecedented cancellations due to extreme weather conditions. One example is the Twin Cities marathon in Minnesota, an event with a 40-year history. In October 2023, this marathon experienced its second cancellation, this time due to extreme heat. The first cancellation occurred in 2020 due to the COVID-19 pandemic. Similarly, the TCS New York City Marathon training series 18M was called off on September 30, 2023, due to severe flooding in New York City. Such disruptions are becoming a grim reality for both organizers and participants.

The latest report from the Intergovernmental Panel on Climate change highlights the alarming trend of increased floods, droughts, storms, and rising temperatures. Human-induced greenhouse gas emissions are contributing to this problem, intensifying heat waves in cities and exacerbating air Pollution issues. Long-distance runners are particularly vulnerable to these extreme conditions.

Long-distance running poses serious health risks, especially in hot and humid conditions. Runners can lose significant amounts of fluid through sweating, leading to dehydration. Dr. Sonia Tolani, an associate professor of Cardiology at Columbia University Medical Center, explains that the body’s cooling mechanism relies on sweat, and the loss of salt through sweating can lead to electrolyte imbalances, which may result in conditions like brain swelling. Heat stroke is another major concern, with symptoms including throbbing headaches, confusion, nausea, and more, making it a significant cause of death in young athletes.

Organizers of marathons and long-distance running events are grappling with the challenge of Climate change impacts, seeking to ensure the safety and well-being of participants. According to the Road Runners Club of America (RRCA) Safe Events Guidelines, events may face cancellation or postponement if the dew point exceeds 80 degrees Fahrenheit at the race’s start time. Additionally, the Air Quality Index (AQI) plays a crucial role in decision-making, with a score above 50 calling for a reduction in the event’s distance to minimize exposure time. If the AQI surpasses 151, the guidelines recommend postponement or cancellation.

Additionally, wildfires, a growing concern driven by Climate change, have gained attention for their impact on air quality. Major sporting events, including marathons, have been postponed due to air quality concerns. Air Pollution can cause respiratory issues and increase the risk of blood clots, particularly concerning for athletes who breathe in more air while training. This issue extends beyond marathons and affects outdoor workers, construction crews, and agricultural laborers, endangering anyone who spends time outdoors.

Long-distance running events are facing a new challenge in the form of Climate change. Extreme weather conditions and deteriorating air quality pose significant health risks for participants and compel organizers to consider postponements or cancellations. As Climate change continues to unfold, it becomes clear that adaptation and flexibility will be essential for the future of marathons.
