Activity Garmin has no start date

I often get this error messages for activities I have created manually in Garmin.
Is there a way you can avoid that?

I filed a ticket about this three months ago. No luck getting an answer so far…

Is your activity also a manually added one? It is - you stated that, doh…

In case someone actually picks it up here, this is my email.

Hi Robert,

I’ve passed the file onto the tech team. Hopefully we can take a look into an figure out what’s getting caught up.

Kind Regards,

I think I’ve brought this up before, but it has not been addressed.

Whenever I add a manual (spinning) activity to Garmin Connect, with data taken from my spinning device, including power, HR and RPM, it does not get through to Xert.

I get a message ‘Activity Garmin Connect Activity xxx has no start date.’

Can you figure out why? I’m attaching a TCX from such an activity – it has a date, from what I can see if I edit it…




See? Nobody cares…

And when I wanted to add another entry, I got this. Infuriating as that is, editing this entry can fix that… I hope the OP will read it and acknowledge that.

Well, that last comment helped, or was it coincidence? I finally did receive feedback from @ManofSteele

Long story short: Garmin manual entries, no matter how complete, are not received well by either Xert or Strava.

The ‘no start date’ error is just Xert’s (wrong) answer to a file it can’t fix - there is a start date, but there are no track points to validate.

Some things can be manually fixed in the output TCX file, but that’s more hassle than adding a manual entry directly into Xert.

Which is only useful for the XSS load, but it beats no entry at all.
