Walking 3 miles typically involves taking between about 6,300 and 7,200 steps, depending on factors such as gender and stride length. For men, assuming an average stride length of 2.5 feet, 3 miles equate to approximately 6,336 steps. For women, with an average stride length of 2.2 feet, it is about 7,206 steps

. Other sources estimate around 6,750 steps for a 3-mile walk at a moderate pace of 3 mph, with women averaging about 6,990 steps and men about 6,630 steps

. Running 3 miles requires fewer steps, roughly 4,600 for men and 4,900 for women, due to longer stride lengths while running

. In summary:

• Walking 3 miles: approximately 6,300 to 7,200 steps (men and women average)
• Running 3 miles: approximately 4,600 to 4,900 steps

The exact number depends on individual height, stride length, walking/running speed, and gender
