Efficiency Index Apps - Garmin & Suunto

If you've picked up Run With Power, or been listening to me on podcasts, you know that speed per watt is the key metric for running power meters, or what I call, Efficiency Index, or EI for short. Chapter 5 in the book is devoted to this topic entirely, and I discuss how a rolling 30 second average of your speed per watt in a race or workout can give you a good idea of how efficiently you're running, or the speed you're getting for the watts you're producing.

In this technology age, we can create these metrics to monitor during a run on our watches or head units, and I have a couple of fans of the book who created the Rolling EI for Garmin and Suunto users. The Suunto apps were created by Toni Cumplido, (twitter: @tonicumpli), so thank you Toni for these! I hope to have more Garmin IQ apps coming.

Here are the links for each, if you're using these products and want to see...

Would ne nice if the Garmin developer could update the app with Forerunner 23x compatibility.

Hi Jim, Do you see a feature like this coming out with Polar v800? I know they aren't the most agreeable to new tech and suggestions for feature updates, but I'd like to think they will consider a variable like this one day soon. Keep up the good work. Cheers, Rob.

What about EI in applications? The only one I see that actually has it is SportTracks. Stryd doesn't even show this metric on their site. Is there a way to create this in WKO4?

Is the Garmin data field still available? Clicking through with the link provided yields an error and I could not find it in IQ app store.
