Marathon organizers are making changes to address hotter race-day conditions linked to a warming climate. With higher temperatures and increased heat stress, organizers are looking at ways to help runners stay safe and comfortable during events.

The coverage agrees that rising heat is affecting how marathons are staged, though the outlets frame the response in practical and cautionary terms. The Independent focuses on the broader climate-driven context and the need for adjustments to keep runners cool. The Winnipeg Free Press similarly highlights that warmer weather is pushing organizers to reconsider logistics and runner support measures, reflecting a shared emphasis on participant well-being as conditions shift.

While neither source provides specific policy details in the material provided, both point to the same underlying development: as temperatures rise, race planners increasingly treat heat management as a central part of marathon preparation, rather than a side consideration.
