Eight Runners Hospitalized in South Korea DMZ Marathon Amid Record Spring Heat

**TL;DR:** Eight runners were taken to hospital after collapsing from heat illness during the DMZ Peace Marathon in Paju, South Korea, as temperatures neared 30°C (86°F)—a rare spring spike. A fire official urged anyone feeling heatstroke symptoms to stop activity and cool down immediately.

**Context:** The DMZ Peace Marathon follows a route close to the heavily fortified border separating South and North Korea. Spring temperatures in the region usually stay mild, but a warm front pushed readings toward 30°C (86°F) on race day, matching the highest mid‑April levels recorded in Seoul since 1907. Meteorologists attributed the spike to a temporary system drawing warm air northward.

**Key Facts:** Twelve runners fell ill along the course, exhibiting convulsions, dizziness, and hyperventilation. Eight of them were transported to hospitals, with a 43‑year‑old requiring intensive care. Race officials reported temperatures approaching 30°C (86°F), far above typical spring averages. A fire official advised participants to “stop exercising immediately and cool down” if heatstroke signs appear.

**What It Means:** The incident highlights the growing risk of extreme weather disrupting endurance events traditionally held in temperate seasons. Organizers may need to revisit start‑time schedules, increase on‑course medical stations, and provide real‑time heat alerts. Going forward, watch for updated safety protocols and potential adjustments to the marathon calendar as climate patterns shift.
