Run Time Calculator: Our run time calculator allows you to estimate how long it will take you to run a specific distance using your previous run times and the run time prediction formula which you have selected.

You can continue reading with this calculator will show you three different equations to find the run time of the events.

## Step by step procedure to calculate the run time and Its formula

Follow these steps to use this run time calculator:

1. Select the run time prediction equation that you want to use.
2. Enter the time and distance of your previous run.
3. Using the drop-down menu or the custom option, enter the distance for which you want to calculate your run time.
4. To get the results, click the calculate button.
One of the most basic formulas for estimating run times is Riegel's equation.
It does not rely on units of measurement, therefore distances and timings do not need to be converted.

Another run time prediction formula is Cameron's equation, which uses data from previous runs to predict future performance.

The VO2 Max Equation is a formula that calculates the amount of oxygen in
This run time formula calculates run times based on the maximum amount of oxygen consumed during incremental exercise, with VO2 max referring to maximum aerobic capacity or maximum oxygen consumption.

Equation 1: Riegel's Equation for Predicting Run Time

T2 = T1 * (D2 / D1)1.06

where,

T1 is your previous run time

D1 is your previous run distance

D2 is the distance you have to calculate a new run time

T2 is your estimated new run time.

You can use any unit of the distance you like as long as all distances are in the same unit of measurement (e.g., all in miles, all in kilometers).

Equation 2: Cameron's Equation

T2 = T1 * [D2 / D1] * [f(D1) / f(D2)]

Here,

T1 is the previous run time

D1 be the previous run distance measured in meters

D2 is the distance to calculate a new run time

T2 is the estimated new run time.

Equation 3: Daniels & Gilbert's Run Time Prediction

The equation is as follows:

VO2 max = (−4.60 + 0.182258 * v + 0.000104 * v2) / (0.8 + 0.1894393 * e−0.012778*t + 0.2989558 * e−0.1932605*t )

Here,

v is the velocity (in meters/min)

t be the time in minutes

The VO2 max rate is described as ml/(kg•min).

### Example of run time calculation

1. Calculate the run time of a 1M of distance is 1miles using Riegel's equation and the previous time is 03hr:10min:15sec with 1km of distance

Solution:

The new event is 1M and Distance(D2) is 1miles

Previous time(T1): 03hr:10min:15sec

The distance is 1km.

By using the Riegel's equation, T2 = T1 * (D2 / D1)1.06

Therefore, the estimated time is 5 hours, 14 minutes, and 46 seconds.
