Q I typically run outdoors, but when it�s hot and humid, I head to the treadmill. Does running on the treadmill burn fewer calories? And will running indoors compromise my training for an upcoming marathon?
A If you�re running at speeds under 9 miles an hour (a very fast 6:40-minute-mile pace), treadmill running burns about the same number of calories as running outdoors, says John Porcari, Ph.D., a professor in the department of exercise and sports science at the University of Wisconsin-La Crosse. But if you run faster than 9 mph, you�ll burn fewer calories on the treadmill. �The difference can be up to 8 percent,� Porcari says. �That�s because you don�t have to overcome wind resistance and because the treadmill belt does propel you along a bit.�"
