MARATHONS ARE ENTERING THE CLIMATE ADAPTATION ERA For decades, marathon calendars were treated as untouchable. Race weekends became part of a city’s identity. Sponsors built annual campaigns around them. Hotels, volunteers, broadcasters, and tens of thousands of runners planned months—sometimes years—in advance. Changing a marathon date wasn’t just an operational decision. It was a business decision. That’s why this week’s announcement from the Twin Cities Marathon feels significant. Beginning in 2027, organizers will move the race from its traditional first Sunday in October to mid-October after years of reviewing weather trends and race-day conditions. The decision follows the cancellation of the 2023 marathon because of forecasted extreme heat and an extensive review of historical climate data. As race director Ed Whetham put it: “The data doesn’t lie.” That may prove to be one of the defining quotes for the future of road racing. Twin Cities isn’t simply reacting to one difficult race day. It’s redesigning one of the country’s premier marathons around the probability of safer conditions. And it isn’t happening in isolation. At this year’s Los Angeles Marathon, temperatures climbed into the 80s. Organizers introduced an early finish option at mile 18, allowing runners to receive a medal without completing the full 26.2 miles. Nearly 1,000 participants chose to end their race there. Before the 2024 U.S. Olympic Marathon Trials in Orlando, elite athletes successfully lobbied USA Track & Field to move the race start from noon to 10 a.m. because of heat concerns. These are no longer isolated contingency plans. They’re signs that race directors are beginning to rethink how marathons are staged. Climate researchers believe the challenge will only grow. A 2026 analysis projected that by 2045, the Chicago Marathon—despite its October race date—will have less than a 25% chance of ideal race-day weather. The New York City Marathon, held in early November, is projected to have less than a 30% chance. For race organizers, the implications stretch far beyond the forecast. Heat affects medical staffing, insurance costs, volunteer operations, sponsorship activations, athlete safety, and ultimately whether an event can deliver the experience runners expect. Moving a marathon by two weeks isn’t a scheduling tweak—it requires coordination with city agencies, tourism partners, sponsors, vendors, broadcasters, and thousands of travelers. Twin Cities President Dean Orton summarized the organization’s thinking simply: “At the end of the day, when you stack up the gains here, I think overall support is going to be understanding.” For generations, marathon calendars were built around tradition. The next generation may be built around data. running.news | Covering the business, culture and future of running.
