intervals.icu

@asynkronxyz We did try with some filters to flip the whole site, but that broke the Vuetify components in weird ways. We are now on newer Vuetify so will give it another try.

@intervalsicu sir, want help adding dark mode? It’s been a feature request for 6 years now[^1], and my eyes can’t take it anymore. [^1]: forum.intervals.icu/t/dark-mode-fo…

The after effects of man-flu. Usual easy 55min trail loop with the dog. Same pace and soggy conditions. HR ~15bpm higher!! Still got some recovering to do before thninking about any tempo or hard efforts :( @intervalsicu compare.

@Anton_Karlssson Unfortunately not yet. It takes a lot of data cleaning to get those charts to work even for power and pace is much messier.

@intervalsicu Can I do something similar for running and compare pace vs HR over time?

Intervals.icu now has very flexible custom training zones for time in zones and workout prescription. Use any activity stream (not just power, HR, pace), any anchors (FTP, LTHR, custom fields) and absolute values #cycling #running

@csahuqui @Strava There are quite a few apps on the /settings/apps page that can connect Intervals.icu and Apple Watch

@intervalsicu @Strava Congrats! Maybe this is the push we needed to get Intervals working with watchOS? ;)

Intervals.icu was awarded the 2025 Data Analysis Award at the Strava Developer Summit! Thanks @Strava ! #cycling #running

@Anton_Karlssson Those charts are built from very cleaned up second-by second data, not average data for the whole ride. Bad data is tossed out, HR lag accounted for etc.

@intervalsicu Great! How can I add the average watt from workouts? When I ride on indoor bikes my Garmin watch doesn't track the power. So I would like to be able to add it manually and then compare power vs HR curve

@Anton_Karlssson Yes several. The /compare page can plot your power vs HR curve for different time periods. Further right = fitter. You can also plot watts/bpm in Z2 on /fitness page. Trending higher = fitter

@intervalsicu Is there any way to display a graph of HR/power development over time? For example, the weekly average from all your sessions

For more on custom zones see the forums: forum.intervals.icu/t/custom-zones…

You can now download and upload activity stream data (power, heart rate, custom streams etc.) in Intervals.icu to edit or analyse data, add custom data to an activity etc. #cycling #running forum.intervals.icu/t/download-and…

@Contrarianhound You can use the @HealthToFit or BreakAway apps to get activities from Apple Health into Intervals.icu

@intervalsicu I can't tell from the web page - does the app integrate natively with the Apple watch and the Apple health/workout apps? Meaning, will it automatically import workout data?

Intervals.icu now has direct integration with Concept2 #row #ski forum.intervals.icu/t/concept2-int…

With version 12.7.1 you can now import your planned workouts from @intervalsicu to your Apple Watch. You must sign out and sign in back to @intervalsicu before importing your planned workouts.
