The Rucking App — More Than a Calculator

I built the original calculator because I wanted my carried weight included in my workout estimates. Now the apps let you tap Start Ruck and follow your workout as you move.

Live GPS tracking: follow distance, elapsed time, average pace, and elevation gain.
Live calorie estimates: account for body weight, carried weight, and workout effort.
Backpack or weighted vest: choose your setup and enter your load.
Background tracking: keep recording your ruck while your phone screen is locked.
Manual calculation: enter your workout details when you already know the distance. No GPS route is required.
Weight-loss planning: explore how your food intake and rucking routine could affect a longer-term goal.

iPhone & Apple Watch

Rucking Calorie Calculator includes optional Apple Health integration, workout history with route maps, sharing, and Lock Screen Live Activities. With permission, it can read body weight and available heart-rate data and save completed rucks to Apple Health.

The Apple Watch companion lets you start and stop a ruck, adjust pack weight, and check progress. Keep your paired iPhone with you for GPS tracking and connected Watch controls.

Rucking Calorie Calculator

Enter your body weight, carried weight, distance, effort level, and pack type to estimate calories burned during a ruck or weighted-vest walk.

Rucking Weight Loss Calculator

Combine your current and target weight, age, height, sex, activity level, calorie intake, and rucking routine to estimate a daily deficit and potential timeline.

These are planning tools, not precise measurements or guaranteed results. The weight-loss calculator uses a simplified model. Avoid counting the same ruck in both your general activity level and your added rucking exercise.

Why I Built This

I’m Preston Shamblen. I went from around 250 pounds to losing 90 pounds by changing what I did consistently: carrying weight outdoors, strength training, and paying attention to nutrition.

Rucking gave me a habit I could keep. Weighted-vest walking is still one of the most reliable tools in my own routine for managing my weight and staying active.

I became an ISSA-certified personal trainer and started building the tools I wanted to use myself. The goal is practical: make it easier to plan a ruck, track the work, and keep showing up.

The tools matter, but the work still happens outside. These are two pieces of gear from my own rucking setup.

Wolf Tactical Adjustable Weighted Vest — a plate-loaded vest for weighted walks and training. #WolfTactical
CamelBak Motherlode Hydration Backpack — hydration and storage for longer outings.
