Incorrect Elevation Data when Pushing Garmin Connect to Strava

James K. Polk — Sun, 05 Jul 2026 01:28:03 GMT

I know the Forerunner 70 does not have a barometric altimeter, but I don't know the exact issue here - when uploading runs directly from Garmin to Strava (using the automatic data push, not by manually adding files), the elevation data registered by Strava ends up 2-3x higher than it should be. For example, a recent run should have registered about ~170' total, but the Strava run, without correction, registered something around 400'. This is happening every time.

I also have a Garmin Forerunner 170 Music (which does have a barometric altimeter) and that watch does not have this issue, so I don't believe it related to this generation of watches.

Manually overriding the elevation via Strava, when available, fixes the issue, but is a pain to do on every single run.

Any tips? Is this something Garmin can fix in an upcoming update?

Thanks!

if the raw altitude datas are very spikey, then on strava it happens (the watch itself is using an internal smoothing for Total Ascent, this is why you see the normal TA value there and not as high as on Strava). The Strava doesnt accept this Garmin calculated TA value if the device has no barometer inbuilt, in this case the Strava is recalculating the TA from the raw altitude datas from FIT file which causes this extremely high final TA . and with the Strava's elevation correction it will be accurate (by the Strava's own ultraaccurate DEM data)

the solution would be a toggle button on Strava to enabled the Elevation Correction by default for every ride (or an advanced option for a specified device only). try to write it to Strava as an idea

Same problem here. Just got my Forerunner 70, took it out on a regular route and found that the elavation gain was almost 3 times the amount it was on my old Forerunner 235 when it transferred to Strava. Has anyone found a fix to this yet? Seems to be a common problem with this version of watch which hasn’t been picked up in any of the reviews I’ve seen.

Thank you. It is very informative.

Stress: How is it calculated?

Sleepy Donald — Mon, 10 Aug 2026 11:10:41 GMT

How is the stress metric calculated? Is it reliable?

Based on my watch, I seem to be highly stressed throughout the day.

RE: Stress: How is it calculated?

You can think of stress level as the inverse of Heart Rate Variability (HRV). HRV is the variations between consecutive heart beats. I once heard this explanation about HRV that really stuck with me (source: Sarah Does Sass: Your heart's secret language: HRV explained):

The heart has a push and pull mode of delivering energy to the rest of the body. When it senses that we might need the energy any moment, like in a stressful situation or during activities, it beats very evenly, it pushes the blood through without much feedback.

When we are more chill, the nervous system can signal when it needs more energy/oxygen, so the heart beats become less regular: it's happening in a more on-demand basis.

So the watch establishes your base HRV value the more you wear it (you can see those ranges in the HRV Status widget). Of course people would be confused by an ever changing number in miliseconds, so Garmin came up with this stress level.

When your HRV is high, then your stress level is very low (close to zero); when your HRV is almost 0, then your stress level is close to 100.

So this way you can understand a bit better how the stress level graph works... it doesn't necessarily mean that you're mentally stressed. It can be that your body is requiring more energy. My stress level spikes and slowly (over hours) decreases after workouts, even after the part that period that Garmin blanks out to avoid confusing people, as we would always have super high stress right after workouts.

If you did some effort, the body needs to work on recovery, which is stress, even if it's the healthy kind of stress. But stress is stress, it does tire us.

Here are two more sources that more or less confim my theory about the relation between HRV and stress:

The Garmin article is a lot less clear about the actual relation than the first article. I formed these theories after paying close attention to my stress levels in the last 8 years, when I started wearing the Forerunner 935, and now the Enduro 3 for 2 years. Hope this helps clear it up a bit. 🙂

Same problem.Have used a Forerunner 55 in the past and there it was ok. Now with my new Forerunner 70 i also have 2-3x too much elevation.

Did check for corrections on elevation, but could not find it in Garmin Connect or in Strava.

[BUG] - Incorrect strength stats

8643112 — Sat, 08 Aug 2026 00:25:25 GMT

I recorded a strength activity using a preprogrammed workout that I was following. I did 8 reps of the dumbbell squat with 25lb weights, but it’s recording my personal record as 24.9lbs and it’s not even showing the ampersand correctly of the activity name. How can I report this bug?

I similarly did dumbbell curls with 10lbs and it went onto Strava as a 9.9 lb weight.

Health Status Not Calibrating

4863843 — Sun, 12 Jul 2026 04:41:33 GMT

Device: Forerunner 70

Firmware: v9.17

Issue Summary

İ have been using the Forerunner 70 for more than a month, and all data is calibrated(HRV baseline, Training Readiness), but the Health Status reading still shows "waiting" with all the data unavialable in the measurements. I don't know what the issue is, and it has not changed since I bought the device.

RE: Health Status Not Calibrating

moschenin — Mon, 03 Aug 2026 20:21:11 GMT

The only problem is that this section has 5 indicators, including temperature. But the 70 and 170 can't read temperature. And the indicator is inactive, gray.
Please fix the unused indicator in Health Status for the 70 and 170, and maybe even the 570.

Forerunner 70 Running Alerts auto adjusting

7140769 — Tue, 14 Jul 2026 09:52:21 GMT

I recently bought the Garmin Forerunner 70, for a general run I use the Alerts settings to set a fast and slow alert. I want to be able to set these 15 seconds apart. e.g. 5:00 per km and 5:15 per km but whenever I do this they auto adjust to be 30 seconds apart. I used to be able to do this on my old Garmin vivoactive 3 can I really not do it on the newer model?

RE: Forerunner 70 Running Alerts auto adjusting

Attila — Sun, 26 Jul 2026 16:02:08 GMT

I can reproduce this issue on my Enduro 3 (I know, very different watch, but it is using the same codebase nowadays).

The gap always readjusts to be at least 30 seconds for me as well. I guess this is to avoid constant buzzing, it's very hard to run more accurate pace than within 30 second, however if you want to annoy yourself then that should be your right. 🙂

An alternative solution is to create a workout in Garmin Connect: https://connect.garmin.com/app/workout/create/running

There you can make a workout with a very long "Run" step, and as far as I see in the "Intensity target" you can make the from-to range arbitrarily small. I managed to set it to 5:14-5:16. Then sync the workout to your watch and start the workout when you run.

RE: Forerunner 70 vs Index Sleep Monitor

Attila — Sun, 26 Jul 2026 15:50:25 GMT

You can check the specs on Garmin's website,

The only difference I can see is the additional skin temperature monitoring (which has very limited use, even if you're a woman).

If you don't mind sleeping with your watch on your wrist, there is basically no difference in using one or the other. Apart from all the hassle being introduced by having to switch between them and sync and charge and update two different devices.

Forerunner 70 vs Index Sleep Monitor

Sleepy Donald — Sat, 25 Jul 2026 07:04:29 GMT

I have a Forerunner 70, and I want to know if it's worth the case to buy an Index Sleep Monitor?

Will this provide me with more data about my sleep?

RE: Health Status Not Calibrating

4863843 — Fri, 24 Jul 2026 17:01:46 GMT

Yesterday, my FR70 started to show the Health Status.

I'm not sure what really caused it since the majority of the required data was already present.

Seems like the issue is resolvedv but I don't know what caused the solution.

9584403 — Thu, 23 Jul 2026 08:45:57 GMT

2 Months?! Why is it that long? It should have been working when hrv got the data.

Btw, thanks for the information. Can you show it that it's working now as a pict?

*Edit, mine is working too now! Needed 1 month for me. Idk what garmin just did, but i believe they did something.

I reply to my own message:

Suddenly this morning Health status started showing! Even without using Pulse Ox.

So this required more like two months than 3 weeks to show up. Basically now it shows HR, HRV, Breathing.

RE: Health Status Not Calibrating

9584403 — Wed, 22 Jul 2026 13:07:15 GMT

All fulfilled but it still doesn't work at all.

My watch never use battery saver mode, heart rate turned on, pulse ox turned on when asleep, already using this watch for 4 weeks.

Still not working.

RE: Health Status Not Calibrating

7685912 — Wed, 22 Jul 2026 10:57:24 GMT

1. I have had this watch for couple months.

2. Wrist heart rate is enabled, haven't touched that setting at all.

3. Had this during sleep for couple days.

However, is it normal that in Health Status those Heart Rate sections and HRV sections show "Waiting" even though they are working else where in my Forerunner 70? So do you mean that I must use Pulse Ox "During Sleep" setting in order to get Heart rate and HRV sections to work in Health Status?

RE: Health Status Not Calibrating

Garmin - DK — Tue, 21 Jul 2026 15:32:41 GMT

If you receive a "No Data" or a waiting message for Health Status or any of the specific metrics within the feature, review the following:

Health Status needs to calibrate for about 3-4 weeks as you wear your device while sleeping to establish the typical ranges of your metrics.
If your device is in battery saver mode or you have wrist heart rate turned off, Health Status will be disabled.
Pulse Ox must be turned on for either during sleep or all day in your device settings to view Pulse Ox data in Health Status.

RE: Health Status Not Calibrating

7685912 — Tue, 21 Jul 2026 10:04:06 GMT

I have same issue that Health status show Waiting still. Been using this watch for like approx two months? 😃
If I open Health Status, it even shows HRV, HR also as Waiting, even though I have HR/HRV features working normally elsewhere..

So seems like software bug here.

RE: Health Status Not Calibrating

9584403 — Mon, 20 Jul 2026 16:30:42 GMT

I have the same problem too.

My pulse ox turned on only when i asleep.

Already used with this setting for 3 weeks or more, but the health status still shows "waiting".

How do i fix it?
