Climate Heat Marathons

Marathon organizers are adjusting to warmer race conditions caused by climate change. Many races are shifting dates, starting earlier or offering shorter runs. For example, the Twin Cities Marathon in Minneapolis-St. Paul plans to move its October race to later in the month starting in 2027. This follows the cancellation of the 2023 race due to record heat. Other marathons, like those in Sioux Falls, South Dakota, and Long Beach, California, have also made changes. Experts say more races will need to adapt as climate change continues. The focus is on ensuring runner safety while maintaining the spirit of these events.
