Help and Support » Calculations

Runalyze estimates for you the Effective VO2max from non-maximal training performances based on the ratio of heart rate and speed. Of course, this estimation is not always accurate, because heart rate depends on many other parameters. Breaks, uphill/downhill, difficult ground conditions, running drills, ... there are numerous possibilities why the estimate of a single workout could be off and in this case you should disable the workout for calculating your shape. You can do so by editing the activity and unchecking "VO2max for shape".

Possible reasons to exclude an activity

Whenever the relationship between heart rate and pace is disturbed by whatever, this can lead to an error in the estimate of Effective VO2max. As soon as this disturbance is significant and has a noticeable effect on the average values, the activity should be excluded for the shape calculation.
