Police in Santa Barbara, California, are investigating after 27 runners sought emergency care following a half-marathon held in the city on Sunday. Santa Barbara Cottage Hospital treated the 27 people at emergency rooms in Santa Barbara and nearby Goleta, and 24 were discharged while three remained in hospital in stable condition as of Monday. The hospital reported the patients had unusual symptoms after the race, and the parent system Cottage Health said it saw a larger than expected number of emergency visits. The race drew several thousand runners on an unusually hot day, with temperatures reportedly reaching 86F (27C) by midday, compared with a typical early November level in the low 70s. Police said the cause of the symptoms has not been confirmed and advised the public that no specific action was recommended, while urging participants who feel unwell to seek medical attention. One runner told KEYT-TV they lost consciousness and could not remember parts of the race, while event director David Monico said 15 people were taken from the medical tent because of dehydration and overheating. The BBC said it had contacted the police, the hospital and the organisers for comment.
