Ruck Weight Calculator

Carrying the right ruck weight is critical whether you’re preparing for a military ruck march, training for a GORUCK challenge, or simply incorporating rucking into your fitness routine. Carry too little, and you won’t get the intended strength and endurance benefits. Carry too much, and you risk overtraining, injury, and poor performance.

That’s where the Ruck Weight Calculator comes in. This tool helps you quickly estimate the ideal ruck load based on your body weight, event type, and optional distance goals. It ensures you’re training at a safe yet effective weight, tailored to your fitness needs and objectives.

How to Use the Ruck Weight Calculator

Using the calculator is simple. Just follow these steps:

1. Enter your body weight (in kilograms or pounds).
2. Choose the event type that best applies to you:
   • Military Standard (33% of body weight)
   • GORUCK Light (minimum ~7–10 kg depending on body size)
   • GORUCK Tough (minimum ~10–20 kg depending on body size)
   • Custom (enter your own percentage of body weight)
3. Optional: Enter your target distance in kilometers.
4. Select your preferred unit (kg or lbs).
5. Click “Calculate.” The tool will display your recommended ruck weight, percentage carried, and conversion in both kilograms and pounds.
6. Review results in a detailed summary, including your body weight, chosen event type, and ruck percentage.
7. Copy or share results easily with the built-in buttons.
8. If needed, reset the calculator to start again.

Practical Example

Let’s say you weigh 80 kg (176 lbs) and are preparing for a GORUCK Tough event.

• You select “GORUCK Tough.”
• The calculator applies 20% of body weight but also ensures the minimum event requirement.
• For 80 kg, 20% = 16 kg, but since the GORUCK Tough minimum is 20 kg, your recommended load is 20 kg (44 lbs).

Now you know the exact weight to train with, helping you build endurance safely while meeting event standards.
