How long 4 km takes, by speed
| speed | time | cadence |
|---|---|---|
| 2 mph | 1 h 15 min | 76 steps/min |
| 3 mph | 50 min | 115 steps/min |
| 3.5 mph | 43 min | 134 steps/min |
| 4 mph | 37 min | 153 steps/min |
Time depends only on speed. The cadence column is how many steps a minute that speed takes at 5′7″ — about 100 a minute is where walking becomes moderate exercise, as steps per minute explains.
Walking or running
These counts are for walking 4 km. Running steps are longer, so a race takes noticeably fewer of them; why the low figures you see quoted are usually running figures is on how many steps are in a mile.
