Marathon Runners Adapt to Rising Global Temperatures
Marathon runners worldwide are adapting their training routines to cope with increasingly extreme weather conditions caused by climate change (Chicago Tribune, 2026-08-23). Heat waves, such as the one over the Fourth of July weekend in Massachusetts, have prompted athletes to invest in cooling gear and adjust their training schedules. For instance, Jen Dimascio-Donohue, training for the New York City Marathon, purchased a $234 cooling headband to combat the heat. Cities like New York, London, and Hong Kong are experiencing more frequent heat waves, while areas like Phoenix face record-breaking summer temperatures. These conditions are forcing runners to train during cooler times of the day, use cooling technologies, and even adapt their pace to avoid heat-related illnesses like heat exhaustion and heatstroke.
