Yes
p-value: p=0.860
Despite a significant increase in marathon participation from 2000 to 2009, the mortality rate remained extremely low and stable at 0.75 deaths per 100,000 finishers.
Mathews et al. (2012) conducted an observational in Marathon runners (n=3,718,336). Marathon running was evaluated on Death during the marathon race and up to 24 hours after finishing (95% CI 0.38-1.13, p=0.860). The overall death rate among US marathon runners from 2000 to 2009 was 0.75 per 100,000 finishers (95% CI, 0.38-1.13), with no significant change over the decade despite increased participation.
