Exertional heatstroke is a growing concern for runners, particularly in events like the Falmouth Road Race, where conditions can lead to dangerously high body temperatures. Participants, like Carolyn Baker, have experienced severe heat-related incidents, highlighting the risks associated with climate change and increasing temperatures expected in the coming decades. Many races lack the necessary medical resources to effectively treat heatstroke, which can cause organ damage or even death if not addressed promptly. Experts emphasize that runners often ignore early signs of heat stress due to a culture of toughness, which can exacerbate the risks. The Falmouth Road Race, featuring over 11,000 participants, serves as a prime example of how hot weather and inadequate preparation can lead to serious health threats. As climate change continues to alter weather patterns, addressing these risks in endurance events becomes critical.
