What It Means

Your VO2 Max of 49.8 ml/kg/min represents the maximum amount of oxygen your body can utilize during intense exercise. It is a key indicator of cardiovascular fitness.

General Classification

Good. Above average fitness for the general population.

Training Implications

To improve this score, focus on high-intensity interval training (HIIT) and consistent aerobic base building.

How to Use

Step-by-step instructions
  1. 1Enter your time from a recent race.
  2. 2Select the race distance.
  3. 3The calculator will estimate your VO2 Max.

Daniels & Gilbert Formula

This calculator uses the standard formula developed by Jack Daniels and Jimmy Gilbert to estimate aerobic capacity from race performance.
Complex regression formula based on velocity and time

Variables:

VVelocity in meters/minute
tTime in minutes

Example

5K in 20:00

Inputs:

Time:20:00
Distance:5 km

Steps:

  1. 1.Velocity: 250 m/min
  2. 2.Calculate oxygen cost of velocity
  3. 3.Calculate % of VO2 Max sustained for 20 mins
  4. 4.Result: ~49.8 ml/kg/min
Result:
49.8

Frequently Asked Questions

What is a good VO2 Max?

Values vary by age and gender. For a 30-year-old male, 40-45 is average, 50+ is good. For a female, 35-40 is average, 45+ is good.

Formula And Variables
How the calculator turns inputs into an answer.

Daniels & Gilbert Formula is the main method behind this calculator. The equation is Complex regression formula based on velocity and time, and the calculator applies it consistently as you change the inputs.

The most important variables are: V is velocity in meters/minute, t is time in minutes. Check those values first if the output looks higher or lower than expected.

How To Use The Result
What to compare before acting on the output.

The worked example on this page uses Time = 20:00, Distance = 5 km and produces 49.8. Use that example as a quick check for the calculation flow before entering your own values.

For practical use, read the vo2 max calculator for runners result as a decision-support number. It is strongest when you compare two or more scenarios using the same units and assumptions.

Data Visualization And Analysis
Different chart views answer different questions about the same calculator output.

Best ways to read the charts

Use a bar chart when you need to compare separate result components, a line or area chart when the output changes across steps or time, and a pie-style distribution when every value is part of one total.

When the page shows multiple chart tabs, start with the overview, then check the ranking view to see which value drives the result most strongly.

What the analysis should tell you

Compare the average, range, highest value, lowest value, and dominant contributor before making a conclusion from the main number alone.

If one value contributes most of the total, test that assumption first. If values are spread evenly, the result is usually driven by the full input set rather than a single outlier.

Common Mistakes
  • Do not mix units unless the calculator explicitly converts them for you.
  • Avoid copying a result without checking whether the inputs describe the same time period, measurement system, or scenario.
  • If the answer looks surprising, change one input at a time so you can identify which assumption is driving the output.
When The Result May Be Inaccurate

The result can be inaccurate if inputs use mixed units, rounded source data, outdated rates, or assumptions that do not match the situation being modeled.

Run a second scenario with conservative inputs when the output will affect a purchase, project, health decision, academic answer, or financial plan.
