For context: That's about 1.4× shorter than a half-marathon.
Distance depends on your height
Your stride length is roughly 0.41 × your height — so a shorter walker covers less ground per step.
| Your height | Stride | Miles | Kilometers |
|---|---|---|---|
| 4'10" (147 cm) — petite | 60.7 cm | 7.54 mi | 12.1 km |
| 5'4" (163 cm) — avg woman | 67.3 cm | 8.37 mi | 13.5 km |
