Periodically I scan the World Famous Message Boards on the popular running website Letsrun.com. Recently one titled "What are some of the biggest running myths" caught my interest.
My favorite running myths:
You should always breath in through your nose and out through your mouth.
Runners with longer legs have an advantage.
Electrolyte replacement during a marathon somehow eliminates cramps, prevents hyponatremia, and improves performance.
You can freeze your lungs running in winter.
You'll catch a cold running in wet, cold weather.
Expensive shoes will reduce injuries.
Stretching prevents soreness.
Running will ruin your knees.
Your body switches over to burning fat after 30 minutes.
