So, for those that have the Garmin Vector 3 pedals, there is a lot of Left/Right balance data in their .fit files. And I’d really like to see something like a Left power graph and a Right power graph much like the regular power graphs. L/R eFTP, L/R power curves, etc.
I am unsure the extent you can get this from any other dual sided power meter.
But bottom line, it’s an incredibly valuable tool if you are coming back from a knee injury, especially something like an ligament injury that causes a fair amount of muscle atrophy.
This works only from data from Garmin ? I have Assioma powermeter… I imagine that via Strava the data about power balance are removed from the activity file … How can i see this data ? I have wahoo bike computer my workouts are send to Strava & Training peaks. And i use Strava auto import to get my activities in Intervals.ICU
Yes unfortunately Strava does not provide that data. You need to get a .fit file into Intervals.icu, either by manual upload (you can download the original file from Strava) or via Garmin Connect (guess not with Wahoo).
I will add Wahoo integration as soon as it is available.
Thanks David, love this idea. I can’t seem to get the Balance chart to display though…I uploaded a workout last night from Garmin Connect, but even when I manually choose to display this chart, I get nothing. Any ideas? Thanks.
It doesn’t have L/R balance data. You can download the original .fit file and upload to https://www.fitfileviewer.com to check these things. Or was it a different activity?
Thanks. Just checked…looks like it doesn’t include the L/R balance data. I had assumed (wrongly, it appears!) that my Wattbike would have been sending this data to Zwift. Never mind.
Just to contribute, I use Assioma Duo, both outdoor with Garmin Edge and indoor with The Sufferfest. I have Strava and Connect associated with Intervals, and both kinds of workouts go to both training platforms.
For outdoors I have R/L balance displayed into Intervals, from indoor (which goes from The Suf to Garmin and Strava) don’t.
Cheers!
That sounds really cool and useful – as a new powermeter user, with an Wahoo Bolt, I was a bit puzzled why the L/R data did not make it into intervals.icu…
Looking at the link to the Wahoo cloud API, this does seem to exist (now)? Or am I missing something?
I.e., is there anything we can do – even if only sending a feature request to Wahoo;-)
In any case, thank you for a cool tool – I am looking forward to get my data into intervals automatically:-)
I had another look at their API docs and its not clear to me that it is possible to get the .fit file for a workout from the API unless I am missing something? You could try using Dropbox to get rides from Wahoo into Intervals.icu.
Thanks @David !
I confess that I have no clue about the Wahoo API. I can/will drop them a note;-)
While I really don’t like dropbox, I’ve already setup an account just for this purpose and connected both Wahoo Element app as well as intervals.icu to it – let’s see what happens on the next ride.
I also kept the Strava connection, as that has more workouts then just the bike rides… Is there anything I should do to ensure that the dropbox fit files take precedence over the Strava data for the same ride?
@David, this is really cool stuff!
One suggestion I’d have for the display of the balance vs. power graph is to allow changing from a scatter plot to a contour/color plot of a 2D histogram of the data. At least in the case of lot’s of data that would provide much more quantitative information on the actual data.
Hmm, it doesn’t … In fact, for todays activity neither the “exported original” from Strava nor the Dropbox import match/replace the Strava activity. That’s because Strava already mingles with the data and the thus the “Strava import” does not match the FIT0-file info. For my specific (very short, 45 min) ride today it’s, e.g., a >2 min difference in duration…
Would it be an option to get the “original FIT” from Strava and then “merge” the data – i.e., use the metadata from Strava (including the link/show to Strava functionality) but do the analysis on the original data in the FIT file (retrieved from Strava)?
Or to merge workouts in such a way that overlap in real/wall time for most of their data?
Unfortunately Strava doesn’t give out the original files via their API.
Intervals.icu considers two activities to be the same if they start within 1 minute of each other. So did you have to manually delete the Strava activity?
