Enter your bodyweight, ruck weight, and unloaded foot-march pace. The tool estimates a loaded pace range between a US Army FM-style rule and an MTI load–speed rule-of-thumb.
Use the marching pace you could sustain unloaded (or lightly loaded) over several miles on similar terrain.
| Model | Description | Pace (min/mi) |
|---|---|---|
| MTI Estimate | Rule-of-thumb: every 1% bodyweight in the pack adds ~6 seconds per mile. | — |
| US Army Estimate | FM-style planning: speed drops as load rises above ~40 lb, scaled to your base pace. | — |
| Range | Practical planning band between the two models. Use conservatively for route cards and mission estimates. | — |
These are estimation tools, not guarantees. Adjust for terrain, climate, movement discipline, and real-time feedback from the team.
