Does Running on a Treadmill Burn More Calories than Outside?

Studies show that there may be a slight caloric advantage to outside running.

There’s no doubt about it: Treadmill running is convenient. Rain, sleet, snow or shine – treadmill runners are untouched by weather conditions (unless, of course, you lose power). But for people looking to lose weight, how does the calorie burn of treadmills compare to running outside?

There have been a number of studies comparing treadmill running to outside running. The studies generally find outdoor running to be slightly advantageous when it comes to calories, though the extent of this advantage varies by speed. For individuals running between 5 and 9 miles per hour, running outside burns somewhere between 0% and 5% more calories. For individuals running at 10 miles per hour and above, running outside burns up to 10% more calories.

If you burn 400 calories inside, it would likely require an additional 0 – 40 calories (depending on your speed) to replicate the same workout outside. All in all, the difference is quite slight – but even small changes add up over time.

Treadmill running burns fewer calories because it’s easier. For one, the treadmill belt assists leg turnover, making it easier to run faster. When you run outside, you must propel your body forward to move. Moreover, when you run outside, you experience wind resistance – a condition that isn’t replicated with treadmill running. To account for these differences and better simulate outdoors running (especially if you are training for an outdoor running event), many people add a 1% to 2% incline on the treadmill.

The bottom line: Regardless of calories, select the type of training that works best for you, your schedule and your personality. Treadmill running isn’t for everyone; many people find it monotonousness and mind-numbing. Likewise, people with joint issues may prefer the extra cushion provided by treadmill running. Whether you do it outside or indoors, running can be a great way to get your cardiovascular exercise.
