Suunto 9 Peak

chrisc92

@brad_olwin I found an old article in french about Firstbeat and Garmin, and the guy noticed that his VO2Max dropped when running in altitude and then he was recomended to run on flat
( don’t know if googgle trad could help there are interesting study references at the end )

Firstbeat VO2 estimation - valid or voodoo?
Maybe you could contact firstbeat i don’t know if someone know if they have forums ?

My opinion is that it is difficult to estimate an oxygen consumption on the field whith such HR devices and GPS.
To record a more reliable metric I tried to run with Stryd power meter , a foot pod sensor based on Power estimation . it has a good protocol to calibrate the critical power (like bike FTP) Power Duration Curve is updated by tracking best efforts in your activity

If not running in two much high grades it provide some Normalized Power , as pace zones or HR zones are difficult to estimate when not running on a track.
Initially I ordered it to have a better instant pace displayed on the S9B because pods are better when calculating pace based on stride. And it turned out that Stryd is much better than Suunto fused speed

Then following this personal curve predictions are more reliable than those based on VO2max percentages

@chrisc92 I have a Stryd and have had one a long time. I even have the first version in an HR monitor. Stryd has major issues on trails as well. I use it for trail hill intervals but that is about it. I could go into many details but not worth it here.

After using the watch for a bit, I have one suggestion for the devs, is it possible to have the menu in infinite loop?
It is a bit annoying when you arrive to your fitness level, to have to go all the way back to the main screen.

@andré-faria you could hold down the middle button to quickly return to main screen.

@andré-faria swipe to go back to the watch face.

Every time I start my custom running mode I am forced to calibrate FusedTrack, even if it was calibrated just few minutes before. The Battery mode at start is always custom (endurance), even if my last set up was performance mode.
Why are the last settings not saved?

isazi

@wotus I have reported to Suunto this bug already. The custom mode remains the default one once used it for the sport mode. Should be fixed (I hope).

Is it too early to ask for a Suunto 9 Peak XL?

I really dig the form factor but it is WAY small compared to the baro…sorry

chrisc92

@brad_olwin oh in trail I think it’s difficult for all products, it depends on elevation but also from the nature of the terrain : sand , mud, rocks have consequences on Running Efficiency. Also woods cause temporary GPS losses, and altitude causes oxygen limitation and hypoxic conditions, more HR for same VO2 consumption.
Vertical speed is more important than pace and specific algorithm should be developped. With Barometer Suunto would have a good platform to make a specific trail sport mode, maybe spO2 could help to determine your acclimation to altitude (Garmin has developed such an index)

@stromdiddily I fully agree with you, keep the same thickness but maybe a bigger screen, maybe 48 mm ? Kind of lighter S7 formfactor ?

I’ll be in for 50mm, a customized bezel and bigger buttons

…I’m skilled in Creo, I could also give a hand there… just to mention it once again

Not if you undo the changes in the custom mode to match performance profile. After this, Perfomance will be the default again.

isazi

@surfboomerang well, should not happen that custom remains the default even if you switch to something else

surfboomerang

@isazi I agree. Last selected would be better.

Thank you guys, I didn’t know of this tricks.
Although they solved the “issue”, I think it would be more natural to just continue moving the menu (and maybe less complicated to implement).

@andré-faria long hold the menu to go back from some places as well

I set intervals 12x(30s int + 15s rec) it is same problem as baro, when you finish interval and reset and press start again it stays at start interval screen until first interval expires. Not that is a big bug but sort of annoying.

isazi

@lexterm77 using Suunto+ also?

@lexterm77 using Suunto+ also?

S Plus Weather Insight, Itensity zone set for power, no itensity target set, Target: distance.

I rememered same type of interval on May 21st on Baro, press start, shows interval 1 on screen, then instead of going to interval screen goes back to start screen where shows start pointed at start button but it actually starts counting. If you just keep going it eventually returns to interval screen.

isazi

@lexterm77 I think this bug is already known, not sure if the issue is S+ now. I’ll check and get back to you.
