Not for most women. The “9 miles” figure assumes 2,000 steps per mile, a 31.7-inch step that fits only people around 6’5″. For women between 5’0″ and 5’8″, 18,000 steps is about 7 to 8 miles, and about 7.5 miles at 5’4″. That’s roughly the length of a long weekend hike.
How Long Does It Take to Walk 18,000 Steps?

| Moderate (3 mph) | about 2 hours 30 minutes |
| Brisk (3.5 mph) | about 2 hours 9 minutes |

What Changes Your Number
- Height and stride: the biggest factor. Measure your own stride for the best estimate.
- Pace: you take slightly longer steps when you walk faster.
- Hills, trails and crowds: these shorten your stride.
- Your tracker: phones and watches can be off by about 5% to 10%.
