Walking vs Running: Which Burns More Calories?
Walking and running are both excellent forms of cardiovascular exercise, but they differ significantly in calorie efficiency and time required. Over the same distance, the calorie burn per unit of distance is surprisingly similar — but because running gets you there in half the time, the calories burned per hour of running are far higher.
For a 154 lb (70 kg) person, walking 5 km at a moderate pace (5 km/h) burns about 245 kcal in 60 minutes, while running the same 5 km at 10 km/h burns approximately 315 kcal in just 30 minutes. If you have limited time, running is more efficient. If you have joint concerns or are building a habit, walking is easier to sustain over the long term.
Walking 10,000 steps daily (approximately 5 miles / 8 km) burns around 300–400 kcal for an average adult. Maintained consistently, this amounts to over 100,000 kcal per year — equivalent to roughly 30 lbs of fat. The best exercise is the one you will actually do consistently.
Frequently Asked Questions
Per unit of distance, calorie burn is similar for both. But running takes half the time, so running burns far more calories per hour than walking.
10,000 steps is about 5 miles (8 km). A 154 lb (70 kg) person burns roughly 300–400 calories, depending on terrain and speed.
Both are effective. Running is more time-efficient for calorie burning. Walking is lower impact and easier to sustain long-term, especially for beginners or those with joint issues.
