Question: how many calories burned in 1 hour power walk?
Answer: Basic Calorie Burn At a healthy power walking pace of about 4.5 miles per hour, a 140-pound person burns about 201 calories every 30 minutes, according to Washington University. This is just about on par with fitness author Ruth Field's estimate of about 346 calories burned per hour on a 3.5 mile-per-hour power walk.
