Farm to Feet: What It Means & How It Works

Farm to feet is a supply-chain concept that aims to shorten and make transparent the journey of animal-based materials, such as wool and leather, from the farm where they are produced to the shoes or socks you wear. In practice, it means a brand can trace a specific raw material back to a specific farm, often paying that farmer a premium for verified quality and ethical practices. This article explains the background, how the model works, how to evaluate a farm-to-feet product, and the common questions people have about it.

Formula

The calculator above works out your average running pace and speed from a finish time and distance. The formulas are:

• Pace (min/km) = Finish time (minutes) ÷ Distance (km)
• Speed (km/h) = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Where:

• Finish time (t) is in minutes.
• Distance (d) is in kilometres.
• Pace is the number of minutes to run one kilometre.
• Speed is the number of kilometres covered in one hour.

Worked Example

Using the default values from the calculator: finish time = 50 minutes, distance = 10 km.

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

So a 50-minute 10 km run gives an average pace of 5:00 per kilometre and an average speed of 12.0 km/h.

When to Use This Calculator

Use this calculator when you have a finish time and a known distance and want to know your average pace or speed. It is useful for training, race planning, or comparing runs of different lengths. For example, a 5 km run in 30 minutes gives a pace of 6:00 min/km, while a 10 km run in 60 minutes gives the same pace but a different total time.

How to Read the Result

The pace result tells you how many minutes and seconds you take per kilometre. A lower pace number means faster running. The speed result tells you how many kilometres you would cover in an hour at that same effort. Both are averages, so your actual speed may vary uphill, downhill, or with wind.

Common Mistakes

• Mixing units: If you measure distance in miles, convert to kilometres first (1 mile = 1.60934 km) before using the formula.
• Using seconds instead of minutes: Convert your finish time to minutes (e.g., 1:30:00 = 90 minutes) before calculating.
• Rounding too early: Keep extra decimal places in intermediate steps to avoid a wrong final pace.

Limits of the Formula

This formula assumes constant speed over the entire distance. It does not account for elevation gain, terrain, rest stops, or changes in pace. For interval training or hilly routes, the average pace is still correct, but it does not tell you about your fastest or slowest segments.

Frequently Asked Questions

What is a good running pace for a beginner?

A beginner might run at 7:00 to 9:00 min/km (about 6.7 to 8.6 km/h). This is a comfortable conversational pace. Faster runners often run 4:00 to 5:30 min/km. The best pace for training is one you can sustain for the distance without excessive fatigue.

How do I convert my pace from min/km to min/mile?

Multiply the min/km pace by 1.60934 to get minutes per mile. For example, 5:00 min/km is about 8:03 per mile. To convert speed, multiply km/h by 0.621371 to get mph.

Does the calculator work for walking too?

Yes, the same formula applies to walking. If you walk 5 km in 50 minutes, your pace is 10:00 min/km and your speed is 6 km/h. Walking pace is typically between 9 and 15 min/km.

Why is my pace different on a treadmill vs outdoors?

Treadmills often display pace based on belt speed, which does not account for wind resistance or terrain. Outdoor running usually requires more effort for the same speed, so your pace may be slower outdoors for the same perceived effort.

Can I use this calculator for a half marathon or marathon?

Yes, enter the total finish time and the race distance. For a half marathon, use 21.0975 km; for a marathon, use 42.195 km. The calculator will give your average pace and speed for the whole race.
