If you can “walk” 8 mph you are already in pretty good shape.
Exactly my point .. you’re actually running, at that point.
Grok agrees ...
To achieve 8,000 steps in 30 minutes, you’d need to move at approximately 7.58 mph (12.19 km/h), which is not feasible by walking alone for most people. This pace suggests jogging or running, as it exceeds typical walking speeds and cadences. If you’re aiming to walk, you’d likely need more time (e.g., 60–80 minutes at a brisk 4 mph pace) to reach 8,000 steps.
8 mph is a 7:30/mile pace. That’s running.
