The host of The New York Times climate newsletter says that taking part in a race in Chicago, in the United States, showed him firsthand how global warming is disrupting running. The piece is titled "A Marathon Runner's Hard Lesson" and is part of the newsletter.
What is known
The available source text is a single introductory sentence. It supports three points: the author raced in Chicago himself, the experience showed him the effect of climate change on the sport, and the story appears in a climate newsletter.
What the source does not say
The teaser does not give the exact name or date of the event, the weather on race day, or the results. It also offers no specific examples of how warming affects how races are run or the health of runners. These details cannot be added reliably without going beyond the source, so they are left out here.
The full analysis and the author's conclusions are available in the original publication on The New York Times website.
