This is an excellent app! I wish the data would give us the detail reads of the index on the app so we don't have to come back, look at the numberand fetch it on the chart.

Thank you for the great application. I missed the Running Index in Garmin a lot. I'm using the app with Fenix 6 pro and despite having weather data turned on, I don't see the influence of the wind on the gauges. The watch has access to weather data because I can see it on the watch face. What am I doing wrong?

2022年4月11日, Rider68

Thanks for your comment. Did you activate in the app settings the "Wind-adjusted Running Index" ? Only when the slider is activated, wind data are used for the correction.

Very useful! I appreciate it has also a plugin for the Garmin Connect android app that allows me to see all the captured data in the standard location (in the app) and in nice graphs! Thank you very much for all the work!

lots of great information my only problem is the lack of ability to change the readout to SAE vs metric.

Proximus Daviticus
2021年3月2日 | 第 1.11 版

So i have a question about the Cardiac Drift in %. How do i read this? I see that it goes up 10, and down -10 and im reading my graph now and it shows my peak to be at -9 then steadily rises to around -5... what does a negative in % mean in cardiac drift?

2021年3月4日, Rider68

Generally the drift is shown in % change relative to a pre-defined basis or reference at the beginning which can be selected in the settings. I can sometimes happen that the HR sensor shows faulty, unnormally high readings at the beginning of your activity (e.g. if the strap is too dry). Once you get more sweaty the HR returns to normal. At the end can lead to negative drift values because the rreference basis was too high.

Great app. Specialy for polar users. Is there any way to enable the power metrics from android app ? I see this future in ios app

Excellent data field, also use HRSS [Heart Rate Stress Score] from Rider68

Thanks for providing this field. I want to try the wind-adjusted speed. I'm using Forerunner 645 Music with SDK 3.2.3 (System/Info). Receive weather data from mobile phone is activated in settings. But wind-equivalent distance is zero after my first two runs. Is there something else to do to receive weather data from my phone?

2021年1月10日, Rider68

Did you activate also "Wind-adjusted Running Index?" If yes, I think that the FR 645 is not supported yet.

It’s a very interesting info but why does require to run in background ?

2020年12月15日, Rider68

Thanks for your comment. Indeed there is no more need for a background permission. I will remove it in the next update.

Thank you Rider88. I really like this feature as a former Polar user. A suggestion: Can we customize what to base cardiac drift from, or maybe get some alternatives for changing the base, like e.g.: 0-10min avg HR/pace relationship (current default), 10-20min, 20-30min, etc. I think the first 10min avg HR/speed relationship isn't so interesting. Generally my HR is low the first 10min, so drift will always occur. Personally I would like to see maybe the 10-20min avg hr-pace ratio and thereafter calculate the drift from that.

2020年11月26日, Rider68

Thanks for you comment. Actually I am currently testing this feature. Once it works I will update the DF.

Great data field, also use HRSS [Heart Rate Stress Score] of the same developer

2020年10月16日 | 第 1.1.3 beta 版

As a former Polar user, I find this data field great. Running index is an excellent measure of running efficiency but unfortunately Garmin does not have anything of their own. But you can have it by using this brilliant data field!

2020年9月23日 | 第 1.0.5 beta 版

Great datafield, i like it very much, and it very quickly became one of my favorites to use! I additionally use the datafield "Heart Rate Stress Score" from the same developer. Because i find both datafields extremely useful in training, and due to Garmin limiting the number of CIQ fields to 2 on many devices, I'd love to have a combo datafield of these two. Maybe this can be a suggestion for a future development :)

David Roberts
2020年8月16日 | 第 1.0.5 beta 版

This is great. As a an original Polar user years ago, Running Index was key to monitoring my improvement in running efficiency. This datafield does exactly that. Perfect. As this index is sport specific, it would be great to see another for swimming or rowing etc.

2020年5月26日 | 第 1.0.5 beta 版

Cool field. Never used polar before, but this seems similar to a vo2max calculation? Garmin Connect does graph the running index per run but not over time. If you use GoldenCheetah you can create a user metric and average the index for each day then graph from there.

2020年5月27日, Rider68

I was looking for that but apparently Garmin does not support such figures from customised values like the running index; sorry...

2020年4月22日 | 第 1.0.5 beta 版

Is it possible to get it on cycle works?

2020年5月7日, Rider68

Unfortunately the algorithm is not suitable for cycling, only for running.

2020年4月14日 | 第 1.0.5 beta 版

As already mentioned that's a killer addition to a Garmin watches for people coming from Polar ecosystem. And for me even absolute value being calculated here matches what Polar used to calculate for me - that's really awesome. So thanks so much for doing it, really appreciate! And now I have 1 suggestion for improvement and 1 question. 1. I guess it might be helpful to add a note in the app's description that Running Index is being only calculated if corresponding "data field" was added to one of the activity's data pages. I.e. it's not enough to just install this app from here. 2. Is there a way to graph Running Index in Garmin Connect? In the app and even more importantly in Garmin's web-service. In the same way as in Polar Flow I may see how Running Index changes with time.

2020年4月18日, Rider68

Many thanks for your feedback. I have updated the description accordingly. To my knowledge there is no way to graph Running Index in the same way as in Polar Flow for trending. I am also missing this but unfortunately this seems not to be supported by Garmin Connect!

Thank you! What is the formula/expression for calculting RI? Just trying to understand how it can be improved.

2020年2月20日, Rider68

Here are some useful explanations for understanding the algorithm:

I get no result with Treadmill profile. I currently use Stryd and Polar H10 with Garmin Fenix 6. Does this work only with GPS?

2020年1月17日, Rider68

Yes, it works only with GPS
