Runner collapses with cardiac arrest during California International Marathon

A woman taking part in the 2025 California International Marathon collapsed with cardiac arrest near the midpoint of the race, Sacramento-area first responders reported.

A woman in her 30s was found unconscious after collapsing during the race, Capt. Mark Nunez of the Sacramento Metropolitan Fire District said in a statement.

Firefighters and emergency medical personnel began CPR and used a defibrillator to revive the woman, he said.

“She regained a pulse, began breathing on her own, and was transported to a local hospital in alert and stable condition,” Nunez said.

He praised bystanders, on-scene emergency medical personnel and firefighters.

“It also reflects the extensive planning and preparation carried out by multiple agencies including the California International Marathon staff, fire, EMS, dispatchers and law enforcement over the past several months to ensure the safety and security of all race participants,” Nunez said.

The incident took place at the midpoint of the race in the Carmichael area, authorities said.
