About ZwiftGPS
About ZwiftGPSDeveloped by Andy Lee and powered by Zwift Insider, ZwiftGPS maps your current position in game, as well as the position of your friends. Clicking a Zwifter shows you the current speed, ride time, wattage, and more.
ZwiftGPS also works with your Zwift ride history and Strava account to pace yourself based on past activities!
It is optimized for use on a second monitor or a mobile device.

Frequently Asked Questions
I’m only seeing myself, but none of the people I follow.
First, make sure people you follow are currently riding! If they are, check and make sure your account isn’t set as a private account, which seems to disable being able to see friends’ locations on course.
Will this show the correct map if I use the world tag hack to ride in an off-schedule world?
Not at this time, since the Zwift API does not tell us which world you are in.
What do the different colored rider dots mean?
The colors are used to display rider w/kg ranges (0-1 W/Kg = grey, 1-2 W/Kg = blue, 2-3 W/Kg = green, 3-4 W/Kg = yellow, 4-5 W/Kg = orange, 5-6 W/Kg = red)
Are there privacy issues we should be concerned about here?
We don’t think so. The app only uses the data made public by Zwift’s API. Zwift has a “private account” option which presumably locks much of this data down, although we have not tested this.
Updates
- 5/15/17: connecting to Strava now works on iPhone/iPad
- 4/24/17: Strava live segments added, plus a world chooser. Details >
- 3/11/17: Better zooming, and there’s also a button (bottom-right) to make the map follow you once you’re zoomed in.Rider fill color is now based on Watts/kg:
0-1 W/Kg = grey
1-2 W/Kg = blue
2-3 W/Kg = green
3-4 W/Kg = yellow
4-5 W/Kg = orange
5-6 W/Kg = red
After 6 W/Kg, it starts flashing between white and red, and the flashing gets faster as it goes ever higher.You can click/tap on a rider to see more stats (distance / speed / power/ heartrate etc).In Chrome on Android, you can double-tap to switch to full screen (hides the browser bar and other chrome). In Android you can also “Add to Home Screen” to get a more app-like experience. - 3/7/17: changes to polling optimizations to solve problems with rider positions not updating consistently. Additional changes include rider name styling to improve readability, addition of Feedback links.
Can’t load any ghost…
Hi, i just discovered the Ghost rider function. Really cool feature. But i think it does not work when using a world hack to ride in another world. Is there a way to fix this? Greetings, Just
Hi Just. Thanks for alerting me to this problem. I have now fixed it, so you should be able to switch worlds and pick a ghost from the new world.
You should, therefore, update your FAQ section which states that this function isn’t there for user selected worlds.
Hi Andy,
Noob question but how do i use this app sounds very helpful for ghosting on the alpe! I have opted in on strava but when i open the zwift gps app to log in it comes up with the error “Please opt-in to sharing Zwift activities with ZwiftGPS”? Am i meant to be in zwift when i try and log in? Im confused and stuck at this point
Thanks hope to hear from you
Hi Endy
Good question. Since the GDPR thing earlier in the year, you now need to give Zwift permission to share your data with ZwiftGPS. You can do that here: https://my.zwift.com/profile/connections (you’ll need to sign-in with your Zwift account).
Scroll to the bottom and you’ll see options to “Opt in” for ZwiftGPS. While you’re there, you might as well opt in for ZwiftPower as well!
Cheers,
Andy
Hi Andy,
Thanks for the reply, I am already opted in to zwiftpower and zwiftgps through zwift its when i go to the zwiftgps app to log in with my zwift ID that nothing is happening… when i try with my zwift ID number it tells me
“Please opt-in to sharing Zwift activities with ZwiftGPS
You’ll need to opt-in before ZwiftGPS can find you riding in Zwift OPT-IN: Zwift Connections”
If i put my rider name in and try to log in it gives me the 404 : not found error
Would like to show you screenshots but can’t do so here.
Sorry Endy, I’m not sure what else I can do. That error will only show if it gets the specific error back from the Zwift API: “partner.not.authorized”. As far as I know that only happens for accounts that are not opted in. There’s no way ZwiftGPS can work around that as it can’t get any data about your account from the API. Are you sure you are using the correct ID for that account?
Yup wrong ID number my bad… thought i had the right one saved from when i did zwift power guess not!
Thanks Andy.
can someone help me?: in zwiftgps only some of my friends are visible others not. I d like to see activities of my preferred friends but i can only see some of them.
Hi Fabio, I’m afraid you’ll need to convince your friends to opt-in to sharing with ZwiftGPS, since they can’t be located otherwise. https://my.zwift.com/profile/connections
NYC support?
I’m a new user. I get “400: Bad Request” when I attempt to login. I confirmed that I am using the correct Zwift ID: just the five digit number without the user prefix.
Hi Bob. Thanks for letting me know. There appeared to be some problem with the auth token, so it was returning 400s for all login attempts. Please try it again now.
Hi. Can’t seem to get the ghost option to work. It just hangs ‘loading’. I have connected to Strava, I have starred the segment. I have tried logging off and back on again etc, etc. Any ideas?
I wasn’t able to reproduce this problem, but I did find some errors in the log that may be related. I have implemented a fix (hopefully), so please let me know if it still happens.
It can take a few seconds to load, but then should give a list of your previous activities in that world.
11/17/18. Another rider and I had issues trying to see both our dots and/or names on the map. One on iPad Safari and one on MacBook Air Safari. Only time I could consistently see the other rider’s dot or name was when he tabbed his browser away from ZwiftGPS to Discord. When he brought the ZwiftGPS browser window current, then his dot would disappear on my screen. We were able to repeat these same experiences no matter what browser I tried, Safari, Chrome, Firefox. Bottom line, when both of us tried viewing the ZwiftGPS map, his dot disappeared. Mine was always there. I started the ride and the other guy selected to ride with me.
Hi Lance,
Thanks for taking the time to report the problems you’ve been having, and also trying to delve in deeper to figure out what was going on.
I will have a look into it, and see if I can reproduce what you’re seeing. It’s a bit baffling though, since it seems to be a scenario I have regularly tested 🙁
I could video capture a few minutes from my viewpoint? I can probably get another Zwifter to volunteer testing a different combination of hardware which might shed some light? Also, FYI, I checked both Notify me of new comments via email and
Notify me of new posts via email but did not receive notifications from your reply. I double-checked the spam folder too.
Right, I have been able to test this exact scenario (two riders who are following each other, using two different browsers), and I was not able to reproduce the problem.
Thanks for offering to capture a video, though your description was quite detailed, so I’m not sure what it would add (unless you think it would).
The behaviour suggests that something about his browser making requests to the server for his rider position, was causing a problem server-side, meaning that your requests were not able to read his position. This sounds vaguely plausible because the positions are cached (for better performance and to avoid making too many requests to Zwift’s servers). However, as mentioned, I can’t reproduce it.
It’s possible it was some transient issue (with my server or Zwift’s). I have restarted my server just in case that helps. It’s also possible that there’s some detail about your or his Zwift account that ZwiftGPS doesn’t handle correctly.
If you find the same problem happening again, please could you make a note of the time, and I’ll have a look in the logs to see if there are any clues.
Hello Andy and thank you for the follow up. Obviously there are many combinations of hardware and methods of viewing ZwiftGPS. Maybe we stumbled upon one such combination that is not reliable. I will try other methods and report back.
And I’m still missing how to do a very important ZwiftGPS feature, the Regroup. I picture this being something each rider has ability to do or is it limited to one rider?
The “Regroup” button on the Ghosts panel is intended to forward/rewind any ghosts you’ve added, so that they’re close to you on the road.
Ghosts Panel? Another unknown for me. Are there instructions somewhere so I don’t have to bug you about these newbie issues?
So what “Regroup” were you referring to?
If you’ve connected ZwiftGPS with Strava, you should get a “ghost” button in the bottom left corner, which will let you add ghosts of you’re previous rides.
No instructions, but I can always consider any ideas you may have for making it more intuitive.
Honestly do not recall where I first saw reference to your “Regroup” feature and did not pickup on the intent was related to the “ghosts of your previous rides”. I was convinced “regroup” would somehow magically regroup the other riders in our Zwift group ride.
Feature Request if possible: Our Zwift “unofficial ride leader” wishes there was a display showing AVERAGE W/KG besides the normal current w/kg we already have on the Zwift game screen. This seems like a calculation that could be created by polling the ride status data, storing in a variable then divided by a loop counter and display the result.
This is great! Is the strava live segments feature expected to work for starred segments besides the zwiftinsider verified segments? I tried it today I only got the verified segments live, not the other ones I starred. Thanks again!
Nov 12, 2018 5pm CST. No matter what browser I try, after typing in user ID, I see 404 error. Tried Chrome, Safari, Firefox, on macOS and Safari on iOS. Everything has been working perfect up until this afternoon.
Thanks for letting me know Lance. I have restarted the server, and all seems back to normal. It seems to be something that happens sometimes when Zwift change something and the auth tokens get invalidated unexpectedly.
Worked fine this morning.
I can see some of my friend, but some didn’t show up ! What can I do ?
Love the service. A question brought up this morning, “do users of ZwiftGPS need to be logged into ZwiftGPS for other ZwiftGPS users to follow their progress on the map?”. As long as the Zwift user enables their opt-in preference and has granted others to follow them, then other ZwiftGPS users can see their “dot” without them having to be logged into ZwiftGPS?
Users do NOT need to be logged into ZwiftGPS for others users to see them. As you said, as long as they’ve opted in to sharing, their friends can see them on ZwiftGPS.
Yes. If you’re opted in, you don’t need to be using it for others to see you.
I hosted a meetup this afternoon and none of the riders including me were displayed on ZwiftGPS. Did a free ride this morning and had no issues with ZiftGPS. All systems go until this afternoon.
my Zwift ID is 19461. I have opted in and re-opted in so many times but ZwiftGPS keep telling me ‘Please opt-in to sharing Zwift Activities with ZwiftGPS.
I’m new to ZwiftGPS, trying to figure it out. I’ve opted in through Zwift and connected to Strava. When I select an event I can see a few people’s dots (presumably those who have opted in) moving around the map. When I select “Free Ride”, the map is empty. I don’t even see my own dot. I assumed that “Free Ride” would show everybody who is currently logged in and riding but not engaged in an active event. I can add ghosts from my Strava feed, but other than them the map is empty. Any ideas what I should do to track myself during a free ride?
Were you actually riding while you were testing this? (I.e. pedaling and moving). Zwift reports anyone who has stopped as offline. In ZwiftGPS, “Free Ride” should just show you and your Followers who have opted-in.
I love this app and thanks for developing it. Recently I notice that only a few of the riders I follow are displayed even though they show as active in the companion app and in the Zwift application map. I have my Activity Privacy Default set as “Everyone”
Thanks for your help.
Richard Treadway.
HI Richard, thanks for the feedback.
ZwiftGPS can only see the position of people who have opted-in to ZwiftGPS, so you’d need to ask your followees to opt in.
Thanks for making this. It used to work for me but no longer shows me on the map while I am riding. I have opted in. Zwiftgps seems to have logged me in correctly as it shows my name.
Using a Windows 10 laptop. Zwift working as it should.
Reboot has no impact. Any suggestions?
Thanks for your work on this app. It’s a great tool.
Hi John. Sometimes the ZwiftGPS server needs restarting, which seems to happen after Zwift have changed something. I’ve restarted it now, so let me know if it still isn’t working for you please.
I love this functionality. And I have a tip for how to use it on a tablet. Normally when you open a web-browser on a tablet it will shut down after a minute of no use. But there are other web-browsers like the “Fully Kiosk Browser” in Android that lets you run the browser in “kiosk” mode and thus avoids shutting off the screen.
So if you have a spare tablet around, run zwiftgps.com in kiosk mode while zwifting.
HI Andy, during a rent ride, all was working well for about 1.5 hours. Then all other riders disappeared. I was still showing on the map. Rebooting zwiftgps.com, rebooting browser, and even rebooting whole PC did not resolve it. However it seemed to work again the next day.
Is there some way to deal with this from my end if it happens again? Thanks again!
Hi John, thanks for reporting this. I’ve noticed that sometimes ZwiftGPS loses its ability to get position data. I can’t reproduce it on demand so I don’t know what causes it and haven’t been able to guess at a workaround. My theory was that it could happen when Zwift update or restart their servers, so ZwiftGPS will re-authenticate and re-aquire its access tokens when they stop working. However, that hasn’t completely resolved the problem. I’m afraid, at the moment the only options are to wait, or else to restart ZwiftGPS at the server (which only I do if I’ve noticed it isn’t working).
Next time you have this problem, if you could record the date and time please, perhaps I can match it up with what’s happening in the logs.
