Climate researchers in France have raised concerns about the potential dangers of extreme heat during the Tour de France, prompting questions about the race's safety and future. According to a report in the scientific journal Nature, rising temperatures could significantly impact riders and spectators, leading to health risks and potential cancellations.
The National Research Institute for Sustainable Development at the University of Montpellier's study highlights a concerning trend. While the Tour de France has historically avoided France's most severe heat, the frequency and intensity of peak summer temperatures are increasing. This shift poses a threat to the race and its participants.
A chilling experience from the author's past illustrates the issue. During the Tour of California in 2013, a rider suffered heat stroke at a scorching 108°F (42°C) in Palm Springs. The incident underscores the real and present danger of extreme heat during cycling events.
The UCI's Extreme Weather Protocol, introduced in 2015, aims to address these concerns. However, it has rarely been activated for high heat, and its effectiveness remains questionable. In 2022, the protocol was applied to a stage in the Tour de France, but only minor adjustments were made, such as extending the time limit and allowing earlier feeding.
The study's findings are alarming. In five out of six regions, the highest historical Wet Bulb Globe Temperature (WBGT) at 3 p.m. has been recorded since 2018. This indicates a significant increase in 'high heat stress' days, aligning with the UCI's threshold for the Extreme Weather Protocol. The authors note that areas like Toulouse, Pau, Bordeaux, Perpignan, and Nîmes, which frequently host Tour de France stages, have a history of high heat stress.
Moreover, new heat stress hotspots are emerging, with Paris and central France areas crossing the UCI's high-risk WBGT threshold of 28°C more frequently. The study recommends planning the race for the morning hours to avoid the hottest part of the day, which could significantly enhance rider and spectator safety.
The dangers of extreme heat are not hypothetical. In 2024, Mark Cavendish and Antonio Tiberi both suffered from heat-related illnesses during the Tour de France and the Vuelta a España, respectively. These incidents highlight the urgent need for action.
The authors conclude by emphasizing the need to reconsider the race's timing and develop more robust hot weather emergency protocols. They also call for educating riders, teams, and spectators about heat safety and recognizing heat-related illnesses. This comprehensive approach is crucial to ensuring the Tour de France's safety and longevity.
