Running Index
Running Index offers an easy way to monitor running performance changes. A running index value is an estimate of maximal aerobic running performance, which is influenced by aerobic fitness and running economy. By recording your Running Index over time, you can monitor progress. Improvement means that running at a given pace requires less of an effort, or that your pace is faster at a given level of exertion.
To receive the most accurate information on your performance, make sure you have set your HRmax value.
Running Index is calculated during every training session when heart rate sensor is in use and the GPS function is on, and when the following requirements apply:
- Sport profile used is a running type sport (Running, Road Running, Trail running etc.)
- Speed should be 6 km/h / 3,75 mi/h or faster and duration 12 minutes minimum
- If you use a stride sensor for speed measurement, the stride sensor must be calibrated.
Calculation begins when you start recording the session. During a session, you may stop twice at traffic lights, for example, without interrupting the calculation. After your session, M400 displays a Running Index value and stores the result in the training summary.
Compare your result to the table below.

The classification is based on a literature review of 62 studies where VO2max was measured directly in healthy adult subjects in the USA, Canada and 7 European countries.

There may be some daily variation in the Running Indexes. Many factors influence Running Index. The value you receive on a given day is affected by changes in running circumstances, for example different surface, wind or temperature, in addition to other factors.
Long-term analysis
The single Running Index values form a trend that predicts your success in running certain distances.
The following chart estimates the duration that a runner can achieve in certain distances when performing maximally. Use your long-term Running Index average in the interpretation of the chart. The prediction is best for those Running Index values that have been received at speed and running circumstances similar to the target performance.
