Garmin Running Power, Programmed Workouts and viewing correct Lap Data: iOS app

By now, most of us who have ever used Garmin Running Power with a programmed workout have found that lap data for running power is incorrect, due to limitations in Connect IQ.

I found an iOS phone/tablet app which will not only display running power for Garmin activities, but will also recalculate the correct lap values for running power, instead of displaying the bad lap data that Garmin stored. (The dev probably caught wind of this issue).

The app is ConnectStats, and it's free for iPhone/iPad:
https://itunes.apple.com/gb/app/conn...581697248?mt=8

It basically has the ability to download all your activities from Garmin/Strava, and display additional information/stats.

I ran a rare programmed workout a couple of days ago, and while the running power on Garmin Connect was wrong as expected, I was pleasantly surprised to see that it "looked right" on ConnectStats: low values for recovery intervals, high values for work intervals, and higher values for faster work intervals. As a sanity check, I noted that the activity average power and the power for the first lap were the same on both GC and ConnectStats, as would be expected. (IOW, it's not some random number that was estimated independently, as you might see in some other apps.)

I know this won't help people who need to see their lap power during an activity, but I guess it's one step in the right direction.

This is the dev's website:

Looks like he also has a free FIT File Viewer for Mac (which may or may not have the same ability); I haven't tried it since I don't have a Mac.

Thanks for the link. The pack of good post run power analysis has been my biggest issue with the running power apps.

No problem. TBH I don't use that app much these days, but it's nice to see that it solves a problem for some users.

0 R_Tellis over 7 years ago

I finally got around to downloading this the other day and it's not showing any running power stats at all. Haven't tried to dig too deep into yet to see what the problem might be though.

I thought ConnectStats can only analyze power data from Stryd and not GCP?

0 WillNorthYork over 7 years ago

I don't use a Stryd, I use the Garmin running power combo field. I was surprised as you are, especially because it recalculates the lap values (although that part makes sense considering the complaints about preprogrammed workouts). For me, ConnectStats displays the average running power from the activity (this seems to match what Garmin reports), and also computes min power, max power and lap power (even for non-workouts, these values are usually slightly different than what Garmin reports -- must be using a different algorithm for averaging).

Not to state the obvious, but I sync from Garmin and not Strava or SportTracks.

Yes, I'm linking directly to Connect. It's pulling and displaying all of the RD-Pod stats but no power. All I see in the laps breakdown is lap distance, lap time, avg pace, cadence, and avg HR.

I'm not seeing anything in the config menu that should cause it to disregard the power data channel n the FIT file either. Maybe I'll try to shoot a message to the developer.

I use the HRM-RUN and not RD-Pod, not that I would expect it to make a difference.

Hi, the garmin power should be supported in ConnectStats, but I had limited testing because I don't have the device. Someone sent me one fit file and I tested using that. So if you have issue with power from garmin, send me a fit file for the activity with the issue and I'll try to fix.

Thanks for the response. I'll send you couple either on my lunch break or later this evening.

I have runs done with both and neither show power stats.
