Why personalisation matters
Generic converters often use a fixed average stride of 2.5 ft or 30 inches to convert steps to miles, which introduces meaningful error for anyone significantly shorter or taller than average. A 160 cm person has a natural walking stride about 13% shorter than a 180 cm person — at 10,000 steps that gap is more than half a mile. For training accuracy, height-based personalisation is worth the extra input.
Pace also shifts the equation substantially. A brisk walk at 4 mph has roughly a 9% longer stride than a slow amble at 2.5 mph. Running adds another 20–25% on top of that. Selecting the right pace band makes the distance estimate meaningfully more accurate.
