Temporary Heart Damage May Explain Marathon Deaths

Yellow journalism.

The risk of dying while running a marathon is very low. One 2007 study, published in the British Medical Journal, looked at 30 years of marathon data and put the risk of dying at 0.8 per 100,000 runners. According to the researchers on that study, running a marathon is half as risky as driving the same route on a normal day.

A new study finds that marathon runners experience temporary heart damage during their 26.2 mile (42.2 kilometer) races. The damage is reversible...

Scare tactics.
