|---|---|---|---|
| 4 | 15:00 | 9:19 | Brisk walk |

| Grade | When to use |
|---|---|
| 0% | Easiest belt setting — add 1% to mimic outdoor air resistance |
| 1% | Common “outdoor match” baseline (Jones & Doust research) |
| 3% | Example: 6 mph @ 3% ≈ 11:12 flat effort |
| 5% | Hill training — ~20% harder pace equivalent vs flat |
| 10% | Steep — shorten duration; hold rails only if needed for safety |

Belt 10:00/mi → flat ≈ 11:12/mi
7:30/mi · 12.87 km/h
Set treadmill ~6.67 mph
8:04/mi · 7.44 mph (5K training pace)
Metric: 10 km/h → 6:00/km (9:39/mi)
