“Think of the local 5K races,” Casa said. “They might have an ambulance there or they might have a nurse or medic or somebody there, but they don’t have a whole medical tent set up to be able to deal with heatstroke.”Heatstroke is a dangerous illness caused by heat and runners are at increasing risk as climate change creates more hot days. It can damage organs and kill if not quickly treated. A lot of races aren’t prepared to offer the right care. (AP Video: Jeff Roberson)

Getting victims into a tub of ice water is the best way to quickly cool them. And it needs to happen fast, with quick diagnoses to treat runners on the spot. Medical staff need rectal thermometers to gauge temperature when skin can be deceptively cool.“I can’t guarantee everything that is going to happen in the future,” Casa said. “But based on over 3,000 cases we’ve tracked, if someone’s temp gets under 104 within 30 minutes of the presentation of heatstroke, no one has ever died.”He said there isn’t good data on how many races do it right. From his decades of experience, very few do, although generally he said care is better now than when he started. Casa suggested governing bodies for racing should publish heat-related recommendations for safety.

Race directors must organize complex events for runners of all ability. Some are big races with lots of resources; others are small local affairs with a shoestring budget. Security, organizing workers and volunteers, tracking runners and medical care all must be assembled and paid for, said Dave McGillivray, who helps direct the Boston Marathon and also advises other race directors.

Runners bear responsibility, too. He recalls grabbing a mic at the 2012 Boston Marathon when it wasPeople walk through the town near the coltan mining quarry in Rubaya, Democratic Republic of Congo, May 9, 2025. (AP Photo/Moses Sawasawa)
