Overview
- A participant collapsed near the north end of the Hoan Bridge during the half marathon on Sunday, received chest compressions and defibrillation on the course, and was taken by ambulance to Froedtert Hospital where he was later pronounced dead.
- The Milwaukee County Medical Examiner identified the runner as 36-year-old John Meise of Waukesha and said no medical history was identified in initial reports.
- Race organizers said established on-course medical and emergency-response protocols were in place, called the death the first associated with the event in its 44-year history, and thanked first responders and volunteers.
- Family members and an online fundraiser described Meise as a devoted father of four and said the collapse was sudden, with loved ones and the local running community now coping with the loss.
- Officials have not released an official cause of death, investigators are awaiting further medical findings, and the incident follows several isolated race-related fatalities reported earlier in 2026 that have drawn attention to sudden collapses at endurance events.
