RuckZone: Rucking Tracker

Rucking is walking with weight. RuckZone measures the weight — not just the walk.

Set your carried load on Apple Watch, start the ruck, and RuckZone tracks what that load actually costs you: energy, intensity, and whether this week is building you up or wearing you down.

CALORIES YOU CAN AUDIT

Energy burned is estimated with published load-carriage research (LCDA and Pandolf), which account for pack weight, walking speed, grade and terrain — not a generic walking estimate scaled by body weight. Pick your surface — pavement, gravel, grass, sand, mud or bog — and the estimate changes with it. RuckZone also writes net energy to Apple Health rather than gross, so your Activity ring is not inflated by the resting metabolism you would have burned anyway. The full method, including its limits, is documented publicly.

LOAD SCORE

One number per ruck, combining weight, distance, time and intensity — so a short heavy ruck and a long light one are finally comparable. Weekly trends show whether your load is progressing steadily or spiking.

BUILT FOR APPLE WATCH

Start an outdoor or indoor ruck from your wrist. Live time, heart rate, distance, pace, carried load, Load Score and zone feedback. The watch runs independently — leave your iPhone at home.

ON YOUR LOCK SCREEN

Rucks started on iPhone stay live in the Dynamic Island and on the Lock Screen: time, distance, pace and load at a glance, with pause and finish without opening the app. Included free.

TRAINING PLANS

Week-by-week progressions that raise load and distance at a rate you can absorb, with guidance after each ruck on what the next one should look like.
