Running Economy


This is a simple data field that measures your relative running economy,which is a value based on how many heart beats it takes to cover a certain distance. It represents how far and how fast you can run for a given amount of energy, i.e. how efficiently you run. Because it is based on heart rate, and incorporates your resting heart rate, it is specific to you. You can use it, for example, by learning what sort of average values you tend to run at and then track improvements over time.</p>

What’s New

Version 1.1:</p><p>• Small changes to the implementation of the underlying formula (also adds further smoothing for current/recent economy)</p><p>• Changed the graph colour and dropped the units</p><p>• Added support for D2 Bravo devices

Nice field. But why does my economy increase when I slow down while climbing a hill? I see my HR drop slightly from say 128 to 120, while at the same time my pace drops dramatically to almost a half or less i.e from 10 to 20 km/h. According to the formula, the resting heart used must be unusually high to get such a result. How can I check what value is used for RHR?

Seems interesting If I understand correctly; low number = bad, High number = good. ...and it is personal/relative what is high and low.

See for more information. As it is relative it is not simple to compare between athletes. It can be useful to track average values for runs over long time periods, as an indicator of general fitness. By doing this, you will learn what range of values you typically run at.
