How to Tweak Your Workouts as the World Gets Hotter →
Crisp, cool weather should be one of the perks of a fall marathon, but in Chicago last October 10, the conditions felt more like a curse: humidity hovering at a muggy 80 percent and a high temp nearing 80. It was the warmest start to the Chicago Marathon since 2007, a year so brutal that hundreds of runners suffered heat issues, including heatstroke, causing race officials to shut down the event. Thankfully, the 2021 race went off as planned, but for many of the 35,000-odd runners—including me—the struggles were still real. At what felt like every mile, I saw people hunched over aid stations and kneeling at medical tents, dealing with cramps, dehydration, and other heat-related maladies. Even after months of training in one of the hottest summers on record, these athletes were no match for the sweltering temperatures. |
