Seen in the news last week:
Marathon runners sometimes suffer fatal heart attacks, but the increasingly popular foot races actually save lives by preventing motor vehicle crashes, a new study says.
They randomly selected 26 established marathons involving more than three million participants. Each 42.2-kilometre race had at least 1,000 runners.
What the researchers found was that the races resulted in 26 sudden cardiac deaths, but because of road closures in the vicinity of the races, 46 motor vehicle fatalities were prevented.
I don’t quite understand the science, but an interesting — if morbid — way to look at marathons.
Another interesting tidbit: Almost half of the heart attacks suffered occurred in the race’s last mile.
