Participating in a marathon carries a small risk of death, estimated at 0.67 per 100,000 finishers, with men at higher risk than women.
What is the risk of death from running a marathon?
The risk of death during or shortly after a marathon is very small, though men are at higher risk than women and deaths tend to occur in the last quarter of the race.
BACKGROUND: Millions of community-dwelling individuals run marathons each year. There are infrequent deaths, which are often reported widely, and may create unnecessary alarm about the potential risks. Equally, sensible planning for such eventualities is important when staging an event. OBJECTIVE: The aim of the review was to determine the risk of death from running a marathon and the likely location of such deaths in order to inform the public of the likely risks and improve planning for such events. DESIGN: Narrative review. DATA SOURCES: Primary: PubMed. Secondary: contact was made with the organisers and medical teams of specific marathons and online data sought where necessary. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies had to report the number of participants and deaths during, or within 24 hours of completing the marathon. Results relevant to half marathons or ultramarathons or other endurance events, such as triathlons, were not included. Deaths due to terrorist activity were not included. RESULTS: The risk of death estimated by these studies was approximately 0.67 per 100 000 finishers, that is, 1 death per 149 968 participants. From those studies that reported deaths by sex, the rate of male deaths was 0.98/100 000 (1 per 102 503) vs 0.41/100 000 (1 per 243 879) in females. Deaths tended to occur in the last quarter of the race. SUMMARY/CONCLUSION: The risk of death from participating in a marathon is small. Men are more at risk than women. Deaths tend to occur later in the race.
Dayer et al. (Sat,) conducted a review in Marathon running. Marathon running was evaluated on Death during or within 24 hours of completing the marathon. Participating in a marathon carries a small risk of death, estimated at 0.67 per 100,000 finishers, with men at higher risk than women.
