What is Weightpace?

Most people already understand distance, speed, and pace.

But what happens when you intentionally add weight?

If you walk 5 miles carrying 20 pounds, your distance still says 5 miles. Your pace might still say 15:00/mi. Neither number tells you that you carried 20 pounds the entire way.

That is what Weightpace is designed to measure.

Weightpace brings load, distance, and time together in one performance metric for movement under load.

Weightpace = Load × Distance ÷ Time

The result is shown as WP.

The easiest way to understand Weightpace is to start with something familiar: speed.

Speed measures how much distance you cover in a certain amount of time.

Speed = Distance ÷ Time

Travel 5 miles in 1 hour:

5 mi ÷ 1 hr = 5 mph

Your speed is 5 mph.

Cover the same 5 miles in 30 minutes and your speed is 10 mph.

Same distance. Less time. Higher speed.

Pace uses the same two measurements, distance and time, but turns them around.

Pace = Time ÷ Distance

If you travel 5 miles in 1 hour:

60 min ÷ 5 mi = 12:00/mi

Your speed is 5 mph.

Your pace is 12:00/mi.

They describe the same movement in two different ways.

Speed tells you how fast you are moving.

Pace tells you how long each mile or kilometer takes.

Suppose you travel those same 5 miles in the same 1 hour, but this time you carry 20 pounds.

Your speed is still 5 mph.

Your pace is still 12:00/mi.

But neither number changed when you added the 20-pound load.

Weightpace adds that missing part.

Weightpace = Load × Distance ÷ Time

Using the same activity:

20 lb × 5 mi ÷ 1 hr = 100 WP

Your Weightpace is 100 WP.

Now the external load is part of the performance measurement.

Remember:

Speed = Distance ÷ Time

And:

Weightpace = Load × Distance ÷ Time

That means Weightpace can also be understood as:

Weightpace = Load × Speed

For the activity above:

20 lb × 5 mph = 100 WP

This is the simplest way to understand what WP measures.

There are two simple ways to increase Weightpace: carry more load or move faster.

Start with:

20 lb × 5 mph = 100 WP

Keep your speed at 5 mph, but increase the load from 20 pounds to 30 pounds:

30 lb × 5 mph = 150 WP

Your speed and pace did not change. The additional load increased your Weightpace.

Now keep the load at 20 pounds, but increase your speed from 5 mph to 6 mph:

20 lb × 6 mph = 120 WP

The load did not change. Moving faster increased your Weightpace.

Carry 30 pounds at 6 mph:

30 lb × 6 mph = 180 WP

Both load and speed increased, so Weightpace increased further.

This is the basic idea behind Weightpace:

Distance is part of the Weightpace formula, but going farther does not automatically produce a higher WP.

Here is why.

Carry 20 pounds for 5 miles in 1 hour:

20 lb × 5 mi ÷ 1 hr = 100 WP

Now go twice as far with the same load, but take twice as long:

20 lb × 10 mi ÷ 2 hr = 100 WP

You traveled twice the distance, but your speed stayed the same:

5 mi ÷ 1 hr = 5 mph

10 mi ÷ 2 hr = 5 mph

So in both activities:

20 lb × 5 mph = 100 WP

Weightpace measures how much loaded distance you complete in a given amount of time, not simply how far you go.

If you double the distance but also take twice as long, your rate of movement stays the same, so your WP stays the same.

The 10-mile activity is still longer and may require considerably more endurance. Weightpace is not saying the two activities are identical.

Think about the familiar numbers you already use.

5 miles tells you distance.

12:00/mi tells you pace.

5 mph tells you speed.

100 WP tells you your rate of movement under load.

A WP result does not replace your distance, pace, time, or load. It gives you another piece of information when external load is part of the activity.

For example:

Together, those numbers describe the activity much better than pace or distance alone.

Weightpace uses intentional external training weight carried during the activity.

Examples include:

Your body weight is not included.

Ordinary items you happen to carry, such as clothing or a phone, are not training load.

Weightpace measures performance with the load you choose. It does not tell you how much weight you should carry.

You can use Weightpace whether you prefer Imperial or Metric units.

To make every WP result comparable, Weightpace standardizes the calculation using pounds, miles, and hours behind the scenes.

For example, suppose you carry 20 pounds for 5 kilometers in 30 minutes.

5 kilometers is approximately 3.1069 miles.

30 minutes is 0.5 hour.

So: 20 lb × 3.1069 mi ÷ 0.5 hr = 124.3 WP

If you enter the same activity using kilograms and kilometers, the result is still 124.3 WP.

The Weightpace App and Weightpace Calculator handle these conversions automatically.

Weightpace gives walking, running, hiking, rucking, and other intentional distance-based movement under external load a consistent performance metric.

It lets you see how your performance changes when you carry more or less load, move faster or slower, or change both at the same time.

You can use WP alongside load, distance, time, and pace to compare similar activities and track your performance over time.

Terrain, elevation, weather, and other conditions can also affect an activity, so those factors still matter when comparing results.

Weightpace does not replace distance or pace. It adds load to the measurement.

And because distance ÷ time is speed:

Weightpace = Load × Speed

Weightpace measures your rate of movement under load.

Start with an activity you already do.

Download the Weightpace App, enter your load, and start moving. The app tracks your distance and time and calculates your pace and WP. When you finish, save your activity to start building your benchmark.

You can also use the Weightpace Calculator to calculate WP from an activity you have already completed.
