Climate Change: Running Against Time in the World’s Top Marathons

New research reveals that climate change is reducing the chances of ideal running conditions at global marathons. Rising temperatures are affecting athletes' performance, with all Abbott World Marathon Majors impacted. Elite runners express concerns over the shift in marathon norms, emphasizing a need for environmental action.

Climate change is increasingly complicating the quest for record-breaking performances at the world's premier marathons, according to recent findings. On the eve of New York City Marathon, concerns are mounting as elite athletes face rising temperatures that are reshaping the sport worldwide.

Research by Climate Central, a U.S.-based non-profit, reveals that 86% of 221 global marathons are projected to experience a decline in optimal running conditions by 2045. This includes all seven Abbott World Marathon Majors, with London's top female finisher Mhairi Maclennan highlighting the growing challenge for elite runners.

The report underscores the importance of specific temperature ranges for peak performance in marathons, yet global warming makes these conditions harder to achieve. Former champions Catherine Ndereba and Ibrahim Hussein stress the importance of environmental stewardship for the future of marathon races.
