Tcx file reading issue

Bug Reports

Hi everyone,

It seems intervals.icu is not able to read correctly my .tcx file. I know the file is not broken, because Strava reads it without any issue:

I tried to get the file from Strava, didn’t work neither.
What could I do to get the a clean data?

The workout can be found here:

Thanks!

what’s the original device that generated that file?

Can you download the file from intervals? the “Fit File” or the “Orginal fit file” links

Looks like an indoor activity. Did you accidentally have GPS still enabled?
If so, or try it anyway, go to Actions on the bottom of the activity page and click on settings - Ignore Velocity data. (might also try ignoring pace and/or time/distance).
I think Intervals is seeing it as an outdoor ride and tries to make sense of the faulty GPS signal.

That one has duplicate points for the same time. I am working on a fix.

Fixed. File had dup track points and watts values as floats e.g. 187.2.

oh ok, thanks David! How can I fix it myself for other files? I was in an hotel with Peloton’s bike, that’s were I got the tcx, and I must do it for other 5-6 files. I actually merged it with my cardio data from my watch, although it should be noticed, that even without the merging, the issue is present.

You can do that on the activity list page. Select the rides and choose Edit → Reprocess File.

Hi all,

I’m having a similar issue with treadmill activites from the Technogym app via Strava - the paces for the intervals show correctly on the Interval Data, but not on the Activity Pace screen. Unfortunately reprocessing the file as above doesn’t seem to fix the problem.

Activities here:

Thanks for any help!

Sorry do you mind posting a bit more info? The pace of the first interval in that first activity is 3:54/km on the activity timeline chart and on the /data page. So I am missing something.

10

Yep sorry David, I wasn’t very clear on that: the pace shown for the intervals above the activity timeline chart is right (as it is on the data page). But on the activity timeline pace chart itself (when you hover over the blue line), the pace is showing as 1:04-1:05/km for the intervals, and as a result on the Activity Pace page all 51 minutes of the activity are registered as having been in Z7/Z5c. It’s a bit odd, and not a major issue - it just makes my ‘time in zones’ look a bit strange!

Thanks for your help.

11

Aha. That file has you running at 15.3 meters/second (55 km/h) which is why the pace trace is wrong. For the Intervals and the distance vs time (pace) curve the distance and time traces are used which is why those values are ok.

I see you have already swapped to HR first for time in zones. That’s probably the best thing to do.

How bizarre! Though nothing that comes out of the Technogym app surprises me now, it’s pretty hopeless.

Cheers David, will stick with that solution - thanks.
