Q What are the odds of my having a fatal heart attack during a race? JS
Fewer than two in 100,000 people die each year during triathlons (mostly from drowning) and four in 1 million during marathons. You’re literally more likely to be struck by lightning. If you’re over 35, your chances are still small but any collapse is more likely to be due to risk factors like high blood pressure or family history, says cardiologist Paul Dorian. If you ever feel dizzy, faint or tight in the chest, see a doc.
