When you say the Strava archive import failed, what happened? I just had a look at your calendar and you have activities from the import (example this one). Click Options and tick the “Source” box on the calendar. The ones marked “Upload” are likely from the import. You can confirm by clicking through and seeing if they link to Strava.
Morning David
Most of the activities say Zwift, some Strava and a few say upload where I’ve had to manually upload the data.Of late, with many of the activities I’ve done on Zwift they have not been automatically transferred across to Intervals and I’ve had to download the .fit file from Strava and import it. Would this be linked to why the data from the link hasn’t been uploaded? The link is for 5 years of data and barring a few that I uploaded manually for rides for the last few months in 2024 there’s no previous data 
Hmm. You are not currently connected to Zwift. However I can see from the logs that you were recently and disconnected 30 mins or so ago.
You have Strava configured to only download “Ride” and “Walk” so the "Virtual Ride"s from Zwift via Strava are being ignored. You need to re-connect Zwift and tick “Download Activities” and make sure the filter is “all activities”. Then re-enable Strava downloads for everything. Intervals.icu will replace the Strava rides with the ones from Zwift and link them together.
The Zwift integration doesn’t support history but new activities should come in.
Did you receive an email from Intervals.icu with a log of what was done for the Strava archive import? It says:
Ignoring activity types not in [Ride, Walk]
So you had that filter on when you ran it. Better to just do “all activities” so your Zwift history will load.
You need to request a new download file from Strava. You won’t get duplicates. Also remember that the import can take a long time (hours).
Thanks for that David
Looks like I have to wait a few days for a new download link from Strava but as soon as I can I will do so

I’ve imported all my data from strava, and this made all my intervals activities available through the API 
I’ve kept strava connected, and also Garmin connected.
However, after my Sunday ride, I now have the activity synced with intervals, but this new activity is not available on the intervals api… is it marked as ‘strava’ via api, and therefore not coming through? my Garmin and Strava are both enabled, I was expecting that future activities (post full import) would be coming through the API given I have Garmin also enabled.
How can i get new activities automatically available through intervals API given that i have both Garmin and Strava enabled? or will i always have to manually import so that it is available through intervals API?
Thanks
Both Garmin and Strava were having some problems yesterday so it is possible the webhook from Garmin was not delivered or lost. Your Saturday ride came in from Garmin without issues. I suggest waiting to see what happens with the next ride. If that works then just download the missed one from Garmin Connect.
These kinds of issues are very rare.
It refuses my archive because of size limitations. Is there a solution or workaround?
You need to paste the link to the archive from the email into the dialog. Intervals.icu will download it and process the files:

I tried to upload/ sync older data from strava as a paying member. Tried different data; without success.
So how Long could it take? Thank You for your help.
I just triggered Strava historical fetch for the last year for you and the Strava API isn’t returning many activities. The most recent is the 21st of October. There weren’t any errors.
Thank you David! That is weird because there Are Daily activities on strava. So I have to Look for another Solution.
Tried importing my Strava archive last night and got some 2022 activitiesc imported, but more recent ones didn’t work. Email said “284 activities created” and “Found 1929 activities”. Any idea why it didnt import more?
I tried to import my old Strava data before June 15, 2024 (going back to 2010). But an email from intervals informed me, that zero activities are imported. This means it doesn´t work. What can I do? I downloaded already the data to MS OneDrive but I failed also to create a proper link to the OneDrive data (error=invalid link).
Or was it a mistake to first download the date from Strava and afterwards use the Strava download link for the import into intervals.icu?
I got the same error message while using dropbox.
You should not download but simply copy the url from the Strava mail in the Intervals -Strava connection dialog. Intervals will take care of the rest.
This is exactly what I did. But maybe mistaken to download the date before using the link. After the download, the orginal link is accepted but no data is imported.
This is the wrong link. You use GMX as mail provider, and it mangles the link
You have to input the direct link.

You are right. Thank you! I oversaw that GMX has changed the link to something else I sent the original email of Strava to another email client and with this other client I could copy a proper link. Many thanks! I´m happy that it is now importing my data back to 2010!

I have another questions. I learned from this thread that the Strava data which was automatically imported is subject to Strava legal restrictions. If I now upload the “own” data through the download link completely, how could I manage if I will have duplicated activities afterwards? In the end I would like to have only Strava files without the legal restrictions in intervals.
