Estimated Time Remaining

Calculate Total Time per Unit and the Speed in different units, for sports results or similar.

Theory

Average speed tends to decrease as distance increases. This is because over longer distances the body has to manage energy more efficiently and external factors (fatigue, need for refueling, breaks) can intervene.

Over long distances, breaks and refueling influence the average speed.

Time per unit is the inverse of the speed: the higher the time for a certain distance, the lower the average speed.

Calculate the estimated time remaining in different units, for sports results or similar.

This calculator helps you estimate the time needed to cover a certain distance, based on your previous performance.

Use

Choose the Measurement System:

Metric
Imperial

There are two modes: Base and All

Base

Select the unit of measurement:

If you have chosen the Metric System, you can enter:

Covered Distance (Kilometers or Meters)
Time (d h m s)
Total Distance (Kilometers or Meters)

If you have chosen the Imperial System, you can enter:

Covered Distance (Miles, Yards or Feet)
Time (d h m s)
Total Distance (Miles, Yards or Feet)

Enter the values and calculate:

If you have chosen the Metric System, you can get:

Time per unit (d h m s)
Speed (km/h)

If you have chosen the Imperial System, you can get:

Time per unit (d h m s)
Speed (mph)

All

Select the unit of measurement:

If you have chosen the Metric System, you can enter:

Covered Distance (Kilometers or Meters)
Time (d h m s)
Total Distance (Kilometers or Meters)

If you have chosen the Imperial System, you can enter:

Covered Distance (Miles, Yards or Feet)
Time (d h m s)
Total Distance (Miles, Yards or Feet)

Enter the values and calculate:

If you have chosen the Metric System, you can get:

Time per unit (d h m s)
Speed (km/h)
Remaining Distance (km)
Remaining Time (d h m s)

If you have chosen the Imperial System, you can get:

Time per unit (d h m s)
Speed (mph)
Remaining Distance (mi)
Remaining Time (d h m s)

Finally

You can enter:

Desired Time (d h m s)

If you have chosen the Metric System, you can get:

Speed for Remaining Distance (km/h)

If you have chosen the Imperial System, you can get:

Speed for Remaining Distance (mph)

Example:

If you run 10 km in 50 minutes, the estimated time for 20 km will be 1 hour and 40 minutes with a speed of 12 km/h
