Marathon-associated sudden cardiac death: a mini review of risk perception, pathophysiological mechanisms, and prevention strategies

Frontiers in Cardiovascular Medicine·2026

Researchers examined patterns and causes of sudden cardiac death during marathon races, analyzing who experiences these events and when they typically occur. This review synthesized existing data on the rare but serious cardiovascular incidents that can happen during long-distance running.

>for runners

The temporal clustering of events near race completion might reflect how cardiovascular stress accumulates over the marathon distance, potentially influencing how runners perceive fatigue signals in those final miles. Understanding that risk patterns vary by age and demographic factors could shape how individual runners interpret their own cardiovascular awareness during training and racing.

Early Cardiac Responses to Half-Marathon Running in Amateur Athletes: Implications for Cardiovascular Health and Safe Exercise Participation

Journal of Functional Morphology and Kinesiology·2026

Researchers examined how the heart responds immediately after a half-marathon in recreational runners, focusing on changes in cardiac function and blood markers of heart stress. They found consistent patterns of altered heart function and elevated stress markers in the first 30 minutes post-race, with some participants showing biomarker levels that exceeded typical reference ranges.

These findings highlight how even recreational endurance efforts create measurable cardiac stress responses that appear in standard medical tests. Runners might consider how post-race cardiac changes could influence medical interpretations if they undergo heart assessments shortly after racing.
