This might be an ignorant comment since I don’t have a Coros device, but I was wondering if any of the bulk import methods could be used, since they support Strava and Garmin Connect…
It also looks like Coros supports Fitness Syncer, which supports a variety of other fitness apps as data sources (not Zwift directly, apparently) as well as cloud storage providers like Google Drive.
Yes, activities can be imported by hand via COROS Training Hub webpage.
On this website there is a import button which triggers a “open file”-dialog. I’m no coder, not my expertise but automation via the Coros api seems to be the way to go.
Good evening,
Since there's no direct integration (thanks to Zwift…),
I use an Android app called "Health Sync" that sends data from Strava to Coros.
Zwift sends data to Strava, and Health Sync sends data from Strava to Coros automatically.
There's an 8-day free trial.
This does not work with Evolab
+1 for COROS!
Currently using the Health Sync method and the imported activities will add up to the Training load but not to other statistics of the day / week.
It is crazy that this is still being requested over 2 years later.
Other cycling apps offer this natively and the Coros support team have been actively trying to engage to make this happen.
Having to manually copy fit files accros between apps is 2025 (nearly 2026) is very poor, especially when you ask for £18 a month for the privilege.
Hi Zwift, you have 15 days left for releasing this feature before the big 2026 years. Or else explaining to your customers why in BIG 2026 you can’t do an API push of a .fit files to Coros.
Thank you very much for your attention
I have actually left Zwift now for ROUVY only because of this issue. ROUVY is seamless with its integration with COROS. The complete lack of communication / ignorance from Zwift on this issue made me make the switch. I’d love to come back to Zwift one day, but only once they integrate with COROS. I expect many offers are the same.
+1 Would be great to have this feature.
Its truly disgraceful that this has still not been implemented.
Especially since Coros seems to be very eager to do the effort on their part.
Zwift is blindsiding its customers, probably because they have been working on their own trainig load and fitness trend in the companion app lately. But they don’t seem to understand that they are achieving the exact opposite of what their goal is: binding customers.
I got a zwift ride trainer during black friday and have been enjoying it so far, but tbh i regret the purchase despite it being a very good trainer.
I did not know there isnt a family subscription plan, now my wife who was planning to use the zwift ride too, has been locked out of zwift and is using mywoosh instead. 
My apple watch broke last week, so i replaced it with a coros pace 4 because i wanted a longer battery life and better GPS. Now i find out it does not work with zwift…
So at this point i think i will switch to rouvy in the near future… go figure 
My apologies for the long read, but i hope zwift sees this and realizes the impact of their “strategic decisions”. What a pity
I would like this integration very much. It should be a very simple task given that COROS already have API:s available and have even been proactive by contacting Zwift. Smaller tasks you should always be able to push up the backlog.
I don’t imagine there’s a business conflict blocking this, because Zwift doesn’t produce sports watches or bike computers to my knowledge..
Really need this!
HAHAHAHAHA
What a shame Zwift, Three years later we have the same problem, your depressing political rules
+1 we need it
