Authorities in Santa Barbara investigated after more than two dozen participants in the Santa Barbara Half Marathon required emergency medical treatment on Sunday. Cottage Health reported that 25 to 27 runners sought care at hospital locations in Santa Barbara and Goleta for symptoms initially described as "unusual" and of "undetermined cause." While the Santa Barbara Police Department opened an investigation following reports from the hospital, the Santa Barbara County Public Health Department later stated the illnesses appeared related to heat and physical exertion rather than contaminated water or a broader public health risk. Most patients have since been discharged, with a small number remaining in stable condition.
