Thank you for the reply

Here we go again. Last Saturday’s Zwift Insider hosted Uber Pretzel event has about 10% or so of the participants with unprocessed data. I’m one of them. Again.

This is another event where we blew our guts out for some sort of virtual reward and it looks like Zwift has dropped the ball again. Like the Cancellara TT and two of the TdZ Stages.

I’ve said this before: The data from our efforts is what we’re doing this for. If Zwift cannot maintain the data reliably, then they need to find someone who can. IIRC, the guys that ran Zwiftpower before didn’t have a problem keeping up with the process. Perhaps they have some answers for ZwiftHQ?

Hey everyone, happy Monday! Hopefully the riding for you all (indoors or out) was great for you.

Looking through this thread, I wanted to give you some information in an effort to let you know what the situation looks like for us here at Zwift HQ. Right now, the biggest issues with ZwiftPower are:

  • Live Data Not Working - We are acutely aware of the massive problem with live data, and how it has what seems like a random propensity to exclude certain riders - some of you more than others - from the results.

  • Post-Race Data Spotty/Not Working - Like the above, we’re aware that the post-race data has also amounted to what you could simply call meaningless after a race. It seems that the data is worse on races where the live data was not working.

Those two points are nothing new, as anyone who’s looked at this thread will have seen; they’re basically a repeat of what I’ve been saying for a while now.

So that of course leads to the obvious: What are we at Zwift doing to fix it, and why has it been going on so long now?

For the eagle-eyed among you, you’ll have seen the snippets where I called out that we are working to implement fixes that will resolve the issue in a more scalable and reliable way in the long term. This is still true. At the moment, we are actively working on this and are exploring our options. We have been in close communication with WTRL about the issue and Martin has been a superstar both in his patience and his provision of data to help us narrow it down.

From a community perspective, I understand where the question “what is Zwift even doing?” is coming from. I, like so many of you, am entrenched in various communities across the internet and they each have their share of parallel situations. For me, there is nothing more vague - and even frustrating at times - than “we hear you, we’re working on it.”

I wish we had a better update right now and we don’t. We are working hard on the issue and will share an update as soon as we have better visibility into the solution.

Thank you all for your understanding, and Ride On!


A lot of words to say little - Try to go for something a little more sincere next time. @xflintx



“We’re Zwifting the ■■■■ out of this.”

No comment regarding reaching out to the old ZP guys to help?

*By the way the word blanked out is the opposite of heaven. No idea why it was censored.


Hey - Not sure if my use case is slightly different but i’ve been directed here by Zwift support. It was brought to my attention after last weeks ZRL that my power numbers were different to that of my team mates (much lower). I record all my rides to my Wahoo headunit to review data in Training Peaks and noticed a 23w discrepancy between that and the ZwiftPower data (20 min power). I did some investigation comparing the same .FIT file that had been used by ZWIFT and it matches (as you would expect) my headunit power. Looking back and examining various ZP data “most” are inaccurate also! I wonder how many others are blissfully unaware this is happening and even more concerning is that rider *could be racing in the the wrong CAT because ZP is not accurately reflecting the power presented in the .FIT file???

Thanks for at least trying to update us @xflintx but really it is lots of exactly what you astutely pointed out is just frustrating as a customer… “we are working on it”

As already asked many times why don’t you consult the guys that built the system who already said they can help and are willing to help… I can only assume Zwift have reasons for not keeping them involved but if so what!?!

Let’s hope the next update has some better news.


@PETER_BRADBURY It looks like your rides are all marked private in Zwift and therefore Zwiftpower is using your live data, not fit file, hence the differences.

Wonder why support couldnt answer that.

Thanks @Dean I didn’t even know that it had to be set to Public for ZP to get the .FIT file rather than use live data (was set to followers). Agreed - they should have know that. Although this thread had opened up a can of worms on the WTRL page with both Glen and James on there lol


By the way @PETER_BRADBURY changing privacy now doesnt retrospectively change Zwiftpower unfortunately - the change will only apply going forward. Cheers. EDIT: that statement applies to race position sorry. I’m unsure whether it will allow stats to be updated.

And in the meantime, WTRL is doing an amazing job despite the data that you do not provide.
But the duathlon league that Zwift is co-organizing and promoting via email to all subscribers cannot work with the crap Zwift Power is not providing.
If you are not technically capable of providing a certain service, do not design events that are based on that service.


@Simone_Chiaretta_BZR I can assure you the Zwift Duathlon format does work. WTRL and the Zwift Tri marketing team spent considerable time testing weeks ago before the ZwiftPower live data pretty much completely died and it worked incredibly well. The fact that it does not work now is a testament to the terrible state that ZwiftPower has been allowed to become. While this is not something Zwift will want to be attributed with, the fix needs to come soon as while the Zwift Duathlon league is affected severely (to say the least) along with other WTRL events (ZRL & WTRL TTT), ALL Zwift Racing is affected. Rider categories are shot (riders getting upgraded that shouldnt be, others not getting upgraded when they should be, ranking points broken, power data incorrect, results incorrect, riders appearing in results 7 days after an event with no data or way to determine if they are supposed to be there… the list goes on)


There are references earlier in updates and even on the forum of;

  • the small team at ZwiftPower

Understand Zwift won’t divulge its hiring strategies, use of consultants etc and whilst throwing more people at a problem doesn’t always help my consideration or care from a consumer perspective for the size of your team at ZwiftPower is very low (however as your personal role as front person I do empathize with you getting all the messages)

Along with this comms have reverted to only post like this and the status page at Zwift says ZwiftPower is operational and their are no known issues.

Realistically there are known issues and https://status.zwift.com/ should reflect this.

After issues spanning back to Nov/Dec I think this issue should be escalated and we should be hearing updates from higher up the hierachy as building a from fresh solution should have been possible in this window.

This is a paid service and whilst I appreciate the company may have other priorities promoting series like the duathlon series without the ability to support the production of results is problematic in building the trust of user base.

Thanks for listening to this feedback - communication, transparency and action are key and at the moment how much of the above is happening is a little bit opaque.



Is there a timeline for the fix?

As a user of this system, I’m not seeing any clear timelines for action. Unfortunately, even though I enjoy duathlons, I’m going to pull out of the duathlon league for now.

I’ll probably also step back from taking part in Zwift racing for a while until I see things back to normal as they were last year. Its a lot of effort for most of us, physical and mental prepping, waking up early in the mornings, giving 100% to these events and then having to deal with broken systems.


Hi Martin, with “you” I meant Zwift and their ability to provide reliable data. They are pushing eRacing and all these racing events, but they are not capable of providing the raw data to make those things happen.
You guys at WTRL are doing an amazing job and I’m sure everything has been tested well in advance, but I think the main issue lies in your sentence

“WTRL and the Zwift Tri marketing team”

As you know I’m a developer as well, and worked on many events/initiatives and almost all the times “marketing” planned on things that it dept couldn’t provide.


This really is affecting the racing community now and needs immediate action from Zwift. A high priority IT incident should warrant daily updates on both here and the service status page as others have said, and you should be working flat out to fix this.

You also need to support WTRL with this because as they have said, it is reflecting badly on them and affecting individuals there personally. Zwift need to own this and prioritise a fix.


Put the whole thing on hold Martin. Your patience is admirable, but when community racing grinds to a halt it should give Zwift the kick up the behind they need.

The result of this situation should be financial risk for Zwift, not you guys having to work ridiculous hours to produce RIGO (Rubbish In, Gold Out)

Also going to bring @Mark_Cote in on this. If it hasn’t already, this should be being escalated to the highest level, and to be honest should have daily status updates and comments from senior management. I am sure you are aware of the impact this could have if the ZRL season was put on the hold, the TTTs stopped and the duathlon binned. This is a Zwift PR disaster waiting to happen.
