Professional cyclists competing in the Tour de France are calling on race organizers to implement earlier start times as extreme heat waves continue to impact the event. Riders have described the conditions as 'insane heat,' with temperatures exceeding 40 degrees Celsius in some stages, posing serious health risks.
Riders speak out on dangerous conditions
Belgian sprinter Tim Merlier, who won the seventh stage on July 10, 2026, between Hagetmau and Bordeaux, emphasized the physical toll. 'It's not just about performance; it's about safety. When you're racing at 50 km/h in 40-degree heat, your body overheats quickly, and recovery becomes almost impossible,' Merlier said after his victory.
Several riders have taken to social media to express concerns, with some warning that the current schedule could lead to heatstroke or worse. The Union Cycliste Internationale (UCI), cycling's governing body, has faced pressure to update its heat policy, which currently only recommends cancellations or modifications when temperatures exceed 42°C.
Impact on performance and health
Medical experts note that prolonged exertion in extreme heat can cause dehydration, muscle cramps, and heat exhaustion. 'When core body temperature rises above 40°C, athletes are at risk of organ damage and collapse,' said Dr. Sophie Laurent, a sports physician consulting for the Tour. 'Earlier starts would significantly reduce the peak temperature exposure.'
The call for change comes as climate change increases the frequency and intensity of heat waves across Europe. A 2025 study by the French meteorological service found that summer temperatures in southern France have risen by an average of 2.5°C since 1960, making the Tour's July window increasingly hazardous.
Organizer response and potential changes
Tour de France director Christian Prudhomme acknowledged the concerns but stopped short of promising immediate changes. 'We are monitoring the situation closely and consulting with teams and medical staff. The safety of riders is our top priority,' he said in a statement. However, riders argue that proactive measures are needed now, not after a tragedy.
The Professional Cyclists Association (CPA) has formally requested that stages be moved to start at 6 a.m. instead of the typical noon start. 'This is not a luxury; it's a necessity,' said CPA president Gianni Bugno. 'We cannot wait for a fatality to act.'
Some teams have already taken independent action, such as providing ice vests before stages and increasing the number of water stations. But riders insist that systemic changes are the only lasting solution.
Broader implications for cycling
The debate mirrors similar discussions in other endurance sports, including marathons and triathlons, which have shifted to earlier start times in hot climates. The Tour de France, as the world's most famous cycling race, could set a precedent for other events.
As the 2026 race continues, all eyes will be on how organizers handle the remaining stages. With temperatures forecast to remain high, the pressure for earlier starts is only expected to grow.
