Santa Barbara Police Probe After 30 Half Marathon Runners Need Care
Police in Santa Barbara opened an investigation after 30 half-marathon participants received medical treatment on November 8. Hospitals reported unusual symptoms, while organizers and county health officials point to heat. All 27 patients who reached emergency rooms have been discharged.
Police in Santa Barbara, California, opened an investigation after 30 participants in the Santa Barbara Half Marathon received medical treatment following the race on Sunday, November 8, 2026. Among those california marathon runners, 27 arrived at hospital emergency departments, according to Cottage Health.
All of those patients have since been discharged, Cottage Health said in a statement on Tuesday.
Police probe "unusual symptoms"
Santa Barbara police said they began the inquiry after Santa Barbara Cottage Hospital reported multiple runners seeking treatment for "unusual symptoms". Neither police nor the hospital has described those symptoms in detail.
Cottage Health said it saw a "larger than expected number of emergency visits", many "with similar symptoms of undetermined cause". A hospital spokesperson said staff were still working out whether heat or other factors were responsible.
The patients arrived at emergency departments in Santa Barbara and Goleta.
Heat the leading explanation
Temperatures were unusually high for November. The temperature reached around 27 degrees Celsius by 10 a.m., and the day's high was 88F (31.1C).
Event director David Monico said organizers transported 15 people from the medical tent to local hospitals. The medical team also treated numerous runners for dehydration and overheating, both on the course and at the finish line. He said there was "no additional information to suggest that the issues some of the participants experienced were caused by anything other than endurance event exertion-related symptoms".
The half-marathon covers about 13 miles, or 21.1 kilometers, along the Pacific Ocean and through downtown Santa Barbara.
County health department timeline
The Santa Barbara County Health Department said the first call for medical help came at about 8:41 a.m. It involved a runner with symptoms consistent with heat exhaustion, such as lightheadedness or feeling faint. More runners along the course then asked for help, and the department said no spectators or bystanders were affected.
The department said the cause remains under investigation. It added that the incident "appears to be an isolated event connected directly to race participation and the heat", with no sign of a broader public health concern.
County environmental health staff had inspected the race's electrolyte drink preparation site on Friday afternoon and Saturday morning, before issuing temporary food facility permits. Inspectors found no violations, and all water supplies and related materials were clean, properly packaged, unopened and sanitary.
County Health Officer Dr. Henning Ansorg urged anyone still unwell to get care. "If you were at the race, either as a participant or spectator, and are still experiencing symptoms of illness, please seek medical attention and follow up with your physician, urgent care or an emergency department," he said.
