Although outcomes have improved with rapid on-site cooling in elite sports and military contexts, data from community sporting events in low-and middle-income countries (LMICs) remain scarce.  \nCase presentation We report a 30-year-old previously healthy Vietnamese male who collapsed during a 5-km community run. He presented with encephalopathy, generalized seizure, metabolic acidosis, acute kidney injury (AKI) (creatinine 149 µmol/L, estimated glomerular filtration rate (eGFR) 53), rhabdomyolysis (creatine kinase (CK) 3745 U/L), and myocardial injury (high-sensitivity troponin I (hs-troponin I) peak 3.87 ng/mL) . The electrocardiogram (ECG) showed incomplete right bundle branch block with minor ectopy, while echocardiography revealed preserved systolic function. With rapid cooling and supportive care, renal, muscular, and cardiac abnormalities resolved. At onemonth follow-up, hs-troponin I and CK had normalized (0 .0016 ng/mL; 155 U/L), creatinine was 81 µmol/L, and ECG was normal, confirming full clinical recovery.  \nConclusion This case illustrates EHS with multiorgan dysfunction successfully managed at a community sporting event in Vietnam. The comprehensive one-month biomarker and cardiac follow-up highlights the potential for full recovery, while emphasizing the need for cost-effective emergency preparedness-including trained staff and rapid cooling strategies-in LMIC community events.  \nKeywords Exertional heat stroke, Multiorgan dysfunction, Rhabdomyolysis, Cardiac injury, Low-and middle-income countries, Emergency preparedness  \n*Correspondence: Ninh Xuan Nguyen [v.ninhnx@vinmec.com](v.ninhnx@vinmec.com)  \n1Emergency Department, Vinmec Central Park International Hospital, Vinmec Healthcare System, Ho Chi Minh City, Vietnam  \n2Intensive Care Unit, Vinmec Central Park International Hospital, Vinmec Healthcare System, Ho Chi Minh City, Vietnam  \n© The Author(s) 2025.
