Advanced Running Metrics on SelfLoops

We now have a set of advanced metrics for runners. There is the Pace of course, but also the GAP (Grade Adjusted Pace) that estimates an equivalent pace when running on flat land. Because running uphill requires extra effort, the GAP shown will be faster than the actual pace you ran. When running downhill, the GAP will be slower than the actual pace. As a reference for GAP, see for example “Pace and Critical Gradient for Hill Runners: An Analysis of Race Records“, Anthony Kay.

In addition there are the Splits, Laps and the possibility to select areas to analyze in more detail.

Set your Goals and Track your Progresses

You can only improve what you measure. And you need to set goals and be able to track your progresses.

We have added the ability to set your weekly goals and track them. You can set your objectives in terms of number of activities, hours spent or distance. We believe we have added an important tools for people that are serious about their trainings.

If you have not done it yet, sign up to our SelfLoops website.



Calculating your Heart Rate Variability with SelfLoops

The SelfLoops HRV application calculates and displays the heart rate variability.

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat (called R-R) intervals. For an intro to HRV see:

The metrics calculated at the moment are: SDNN, RMSSD, pNN50, AVNN.

To use the application you need a Bluetooth Low Energy heart rate monitor. We have personally tested the application with the Viiiva, Wahoo BlueHR and Polar H7 heart rate monitors.
The Viiiva is available at our store:

If you record the session you will be able to export the data, saved in csv format, to Dropbox, Google Drive, by email etc, and open it using Microsoft Excel, a text editor, Apple Numbers.

By using the application you expressly agree that SelfLoops is not providing medical advice with this application. Please, consult or ask for the advice to your physician or other medical professionals for any health related questions.




Announcing lap support and data visualization improvements

We are constantly working to improve our advanced platform for performance analysis. Today we have introduced laps support and improvements on how the graphs show data.

You can now select the lap number and highlight the segment in the graph. For each lap we have calculated several metrics such as duration, elevation, average speed, power and cadence. You can visualize the lap in the map as well.

Regarding the improvements with the graphs, we have maximized the information visualized at glance. Furthermore, the zoom function allows to show every single data point of the activity, reaching the maximum level of accuracy possible.
