Anyone able to give me a steer on accuracy across devices on Strava? Over the last few months I have regularly run with a mate who uses Strava on a Garmin watch and his Android phone, whilst I have only ever used my iphone (a number of models, currrntly 11) over the years. What we are finding is there are variances between them all – nothing new here. However, my Strava app from my iPhone is showing a variance of some 3minutes or so over 10km’s versus his Garmin and Android phone – as in he’s finished and I’ve still got just under 1km left to go. So what gives? Hate to be a Strava **** but this seems excessive.
Run faster?
Aye, run faster so you finish same time as him.
Garmin likely to be most accurate as phone GPS isn't as good. Also I'm sure the Strava app does some smoothing of data points that changes things as well...
Garmin can use more than one GPS network. My basic 45 is set for (US) GPS and Galileo. Glonass is also an option.
I do run faster. He’s slower, however, we run together, I always finish ahead, and his garmin is saying he’s faster by several minutes over 10k. Is my iPhone gps that poor? If I used his garmin I could beat my pb’s which seems utter tosh to me.
So you know you are faster, he knows you are faster but the world doesn't?
Borrow his watch?
Time your run on a stopwatch to confirm what the real time is.
Presumably yours is under reporting (relatively) distance by the same amount?
In which case looks like yours is logging GPS location less frequently or smoothing the track. Can this be adjusted in the settings?
If you were to look at a straight section would it appear more accurate?

Pretty much any recent decent Android phone does this as well. Mostly GPS and Glonass but more now also getting Galileo support. Would be surprised if an IPhone did not have this feature.
Edit, 4s onwards has Glonass, 8/X for Galileo
A classic case of self delusion.
He is faster.
He does finish first.
Your mind cannot accept this so builds the illusion that you ran alongside him.
I think this may be related to your childhood fantasies about your mother.

The stopwatch doesn’t help much if it’s distance over time. What I need is a definitive distance like a park run and measure it there I suppose.
Are you comparing moving time or elapsed time.
Slight hijack, I don't subscribe to Strava but have obviously linked my Garmin watch up at some time as it has recorded my recent swims but whenever I try to view the activities I get a dialog box blocking the screen telling me to subscribe without any way of clearing it to actually view the data.
Is this an 'improvement' since I last used Strava or can I get rid of it?

Well, there is one way to clear it. You’ll kick yourself when you find out what it is.
🙂
Perhaps I should have added - without subscribing
Looks like your trying to access ‘training log’ which is a subscriber option.
‘training calendar’ is free…not sure what the difference is.
I used a Garmin gps and the android phone app simultaneously years ago when the Garmin wasn't uploading rides to Strava for some reason. This was on mtb rides with loads of shorter segments, most of which were under tree cover so I wasn't expecting a perfect match on times. It wasn't consistently faster on one device either, sometimes the app would be over 30 seconds faster on segments that took under 2 minutes, other times the Garmin would be by the same margins and to top it off I got a KOM up a short but steep climb that I didn't actually ride up. Not sure if the multiple signals were confusing each other as I've had similar issues riding in large groups (starting together and finishing way ahead of people but ending up with a slower segment time)but I stopped caring after the KOM. It's not accurate enough to worry about while using in the woods, I'd expect it to be better out in the open over 10km though. I still use it but mainly to help find new places to ride
Wow, “world class acciden, thanks for the appalling insight, young man.
I pay for Strava, he doesn’t, but I don’t know how that would make a difference to basic tracking. Certainly wouldn’t expect an almost 1km difference.
Forget about accuracy on MTB.
I suspect in this case the phone or app is struggling and running slowly. The OS app on my phone does this. When ss the App to show my location it crawls slowly across the screen to my location. I really don't think a gps in the open can be a kilometre out.
This website is the only real data i've ever seen on gps accuracy

A few take aways.
On the models he tested a an iphone is more accurate than a garmin fenix watch. Simple reason is that watches are to small to get a reasonable signal
The use of the Russisn satellites has reduced accuracy
Thanks for linky Ampthill.
