Ruck Score
One number for any kind of ruck.
Ruck Score is Ruckly's main training metric. It turns a session into a single, comparable number — so a short heavy ruck and a long light one can finally be measured against each other.
A practical training-strain score, not a step count.
Distance, movement time, body-relative load, terrain, and pace are the biggest drivers. Larger relative load earns stronger credit, so a short heavy ruck can outrank a modestly longer moderate one.
It isn’t a simple miles-times-weight total, an exact calorie count, or a precise lab measurement. It’s a single, honest summary you can compare across sessions over time.

The factors behind the number
Distance & movement time
The foundation of every session.
Body-relative load
Pack weight interpreted against your body weight, so 30 lb means different things for different people.
Carry type
Hip pack, vest, or shoulder carry — because the same weight doesn't feel the same.
Pace
Expectations blend from a faster unloaded baseline toward loaded pacing as relative load grows.
Elevation gain
Hillier routes earn a modest lift for the added work.
Consistency
Recent active-day consistency can factor in when enabled.
Ruck Intensity
How demanding the load was, for you.
Ruck Intensity is a load-focused companion to Ruck Score. It's most useful at the start of a session, when you're deciding whether today is light endurance work, a normal training ruck, or a heavier effort.
Light
Easier loaded work.
Moderate
Steady, sustainable loaded work.
Heavy
Meaningfully demanding loaded work.
Strenuous
High-demand work to use selectively.
