Suunto 9 baro very low elevation gain vs other brands
-
So, I’m supposed to run 21 miles of hilly trails on Saturday. Should I wear the Ambit3 Peak and the 9 Baro? Has anyone done a direct comparison?
-
@fazel
yes, before I gave my A3PS to a good friend and before (!) the S9B firmware has been updated to improve the alti summary if I remember correct.
please keep us updated! -
Should I wear the Ambit3 Peak and the 9 Baro?
Absolutely.
Has anyone done a direct comparison?
On those “21 miles of hilly trails”? Probably not.
I’m sure you can post a detailed analysis. Monday morning will do. Or by noon. Go easy on yourself.
-
@Fenr1r “Hilly” for me. I think we are doing just under three loops. The 50K is four full loops and 4900’ according to the Ambit when I wore it for the race.

Okay @Fenr1r @TELE-HO I’ll plan on wearing both watches.

Sorry all @stromdiddily @sky-runner @fazel @TELE-HO @Oktan @Dimitrios-Kanellopoulos , I would like this to end… I find NO differences between A3P, S7 and S9B. Here ya go, a SkiMo and a Trail Run.
SkiMo
Trail Run : A3P and S9B had FusedAlti kick in as you can see.

@Brad_Olwin me too. Thanks buddy. This is much appreciated
-
@Brad_Olwin the “issue” isn’t with bigger/distinguished climbs.
Same day, just over 5 mile route on rolling type terrain…22% difference in altitude.

I often compare my altitude gain with corrections in TrainingPeaks, which I find highly accurate. I do not see this problem with my S9B as you can see below for runs with little altitude gain…I have dozens of these runs too if not hundreds. In fact, I find the S9B overestimates altitude gains on low altitude runs.

@Brad_Olwin your experience does not match my own. But I will leave this topic here.
May “missing” elevation be the worst of our problems in 2021

My point from your last post was the A3P may not be providing the “correct” altitude gain/loss for comparison. I agree that larger gains/losses typically are more accurate for me and the low altitude runs are substantially more variable. However, when comparing with correction algorithms I find the watches are overestimating more often than underestimating. Altitude is tough to get correct and my benchmarks when running or on skis is to compare the actual summit altitude with the watch, the watches are often quite close. As has been discussed before, clothing, wind, and I suspect arm movements affect the calculations and the sensor. In my experience none of the Suunto watches I have are different from each other. My only other comparison is with an Apple Watch and I found excellent agreement with gain/loss on Apple Watches compared to Suunto. I can post a large number of those comparisons too.
On a final note, many of you know I field test for Suunto. This is part of the field testing and many testers compare more than one brand. Based on what I know and what I have observed from my experience and others I don’t believe there is a consistent problem here with watches that have barometers. The GPS altitude watches are another story and I have a different opinion there.

@Brad_Olwin how are you running both watches? Pairing and unpairing in Suunto App? I’m still likely to run with both watches to satisfy my own curiosity. Nice “hill” repeats

Thanks @fazel!. I run often with 2, 3 or 4 watches. Two on one arm, one on one wrist and holding one or one under a hat. I connect/disconnect all to SA on one iPhone and delete all duplicates. I have my exercises set to private so they post only when I have edited those out I am not keeping…daily routine of a tester…

@Brad_Olwin Thank you!

@Brad_Olwin Thank you!
Sure, sometimes not all that much fun when I am hitting the lap button on 2 watches. Today I used S7 and S9B for hill repeats lap button on S7 and testing S9B SuuntoPlus Climb, which lags behind a bit unfortunately. Here is altitude, HR (both on OHR, S7 is better but not perfect) and Stryd watts. S7 OHR lagged on the first and 3rd intervals, S9 OHR too high at the beginning. Watts were good!
Workout after warm up: 1 mi uphill, 0.75 mi downhill, 2 min rest, 0.75 mi uphill, 0.5 mi downhill, 2 min rest, 0.5 mi uphill, 1 mi downhill, 2min rest and cool down.

@Brad_Olwin holy moly. I checked some runs on TP after I read your first reply of the day and noticed the corrections look staggered some. I’m wondering if you’ve ever seen that? I was thinking it might have something to do with using the Stryd for distance and the watch drawing the GPS track on top of it?
Like this…
-
@fazel FusedAlti will continuously correct so the staggered start is likely getting the altitude dialed in, I often see the same and you can see that in my post from TP here. I tend not to worry about it too much. My experience with Stryd for distance is not great, way short on trails. All of my posts here are trails, I do all my interval training on trails (sometimes wide and flat or wide and hilly like today) but hardly ever pavement. If your Stryd is accurate that may not be a bad idea. I have my Stryd paired as a powerpod only. If you pair as a footpod, the Stryd distance, pace and cadence will override the GPS data. Make sure you set auto calibration to off in the footpod menu or it will mess up the Stryd metrics for distance and pace.
Edited per your photo…I have never seen this! That does not look good. Do you have pause or auto pause on? I see breaks in the corrected.
-
@Brad_Olwin so what is your advice for someone like me who needs it paired as a foot pod for the treadmill and runs gravel roads far more often then trails? The way I see it I could
- leave it paired as a foot pod but only use it for the treadmill
- leave it paired as foot pod, use it for the treadmill and roads but not trails
- pair it as a power pod for outdoor use, then disconnect and re-pair as foot pod for treadmill use
Correct?

Test your distances with and without the Stryd on pavement and trail. Just run without and with, I would leave connected as footpod. If you find discrepancies then you can decide.

@Fenr1r no detailed analysis yet, but I can tell you they were within 6%.
- 9 Baro: 2549’ of ascent
- Ambit3 Peak: 2726’ of ascent
- Buddy’s Garmin 920XT: 2703’ of ascent
- Buddy’s Garmin 235: 2558’ of ascent (no barometer)
What is more interesting are the distances.
- 9 Baro paired to Stryd: 22.74 miles
- Ambit3 Peak via GPS: 21.58 miles
- Buddy’s Garmin 920XT: 21.00 miles
- Buddy’s Garmin 235: 20.83 miles
Wow - the Ambit draws pretty tracks…

Is there an email / link to support contact form (I looked and didnt found one), where users can complain about the elevation issue?
