Maximum activity duration (storage space)
-
@MKPotts Since the 9PP can record for 70h with 1s GPS fix in Endurance mode with OHR fully functional you should get at least 70h of recording. Assuming there is some buffer 80h to 90h might be ok. I typically do not go over 48h for a single activity.
Unless you hear from Suunto I would break up a 120h into two 60h sessions.
You can charge during the run but it is very easy to move the charger to stop charging.With an event that long, I assume there are sleep sessions. That would be an optimal time for charging (the watch charges very fast) and if necessary to sync 1/2 of the activity. I will ask Suunto about this as well, I am curious.

Thanks all for the responses.
Support replied again to say that the S9PP can store an activity up to 140hrs long when in endurance mode. I’m not sure if that is with or without OHR data but I would turn OHR off anyway for races this long. And I understand that unlike the S9B/S9P, route navigation can be used in endurance mode with the S9PP.
@Brad_Olwin you’re absolutely right, I do have to sleep on races that go through more than two nights and have previously split the activity as you suggested. But as sleep deprivation becomes a struggle in the later stages, it’s helpful to have the time and distance data “live” in the watch if I can keep it running.
I’ll order a S9PP and, assuming it arrives in time (my race starts on 15th Jan), let you know how I get on with it. -
@MKPotts very interesting, thanks for reporting the answer from support in the forum!

@MKPotts Please give us a report! And I would love to know which race, I have never done one that long. AFAIK in Endurance mode HR is on so the watch is capable of 140h with HR. Up to you whether or not you use it. The 9PP charges extremely fast so you should be able to charge when sleeping or at a longer aid stop. You should only need one full charge in Endurance mode.
The Endurance mode for the 9PP does not used FusedTrack and instead only uses GPS/QZSS with no other satellite systems engaged at 1s fix. Thus, there are no issues using Navigation. Hurray! As an aside I would not use autolap as the constant vibration/tone every mi/km does reduce battery life. I doubt you use it on long races anyway.

@Brad_Olwin
The race is the (Montane) Spine Race - a UK race that takes a roughly 435km route across the hills of Northern England. I’ve done it it winter and summer - but darkness (15-16hrs each day), ground conditions and weather make it a lot slower in winter.
For the S9PP storage space, Suunto came back to me again to say that the 140hr figure they gave is wrong. Figures they’ve given me now are:
Performance - 65hrs with OHR
Endurance - at least 70hrs (i.e. battery duration) with OHR
More without OHR data but they don’t know how much more. I’d guess 20-25% more based on what I’ve seen with my S9B/P, so maybe 85hrs.
The S9PP I ordered has already shipped, so I’ll need to decide if I keep it or send it back. The better battery will still be an advantage for the 30-60hr races I do. -
@MKPotts
out of curiosity: do you have an alternative on your radar?
I mean it is a crazy long race. are competitors able to record and store this amount of data?living sideways

@freeheeler I suppose garmins that can store 16GB of music certainly can store 200h race.
-
@DMytro
well, maybe, if storage space is shared -
@sartoric true, I thought the same. So maybe it can’t, but it seems to be a shameful handicap.
-
@DMytro pretty sure you can store very large activities on modern Garmin watches, they have lots of storage, even more than 32G for devices with maps. What I don’t know is if there is a limit on single file size, if they can otherwise split an activity into multiple ones, etc. But I bet you can record a 120h activity with a recent and high performance Garmin watch. Hopefully this will be possible with future Suunto watches, equipped with more storage.

@freeheeler
When I did the same race in the summer I used a Garmin Enduro and it stored and synced the 84hr activity.
But other than that it was terrible. It couldn’t accurately display a route track, so was of little use for detailed night navigation (often at least 30-40m off the actual route). Luckily I had my S9P as backup on my other wrist. The Enduro also froze twice in the race - something that has never happened with any of my Suuntos.
Spent months going back and forward with Garmin support about route navigation problems but got nowhere. I think it’s some legacy limitation with the number of route points the watch can handle.
Most other competitors use either Garmin Fenix 6/6X (now 7/7X) or Coros Vertix. But after my experience with the Enduro I’m not going to try another Garmin watch.
I haven’t sold the Enduro yet so if I don’t keep the the S9PP I’ll probably use the Enduro to record and my S9P for navigation. -

Don’t know about s9p, but my s9 often has the same behavior in the mountains due to the GPS reception quality. On the flat/open areas it obviously performes much better, rarely diverging too far off trail.

@DMytro
I’ve not had that problem with my S9B or S9P.
With the Enduro, that definitely wasn’t the problem. If I followed a path and ignored the route track, the breadcrumbs showed exactly where I’d been (so gnss signal was good). It was the uploaded track that was wrong because the watch was removing many of the track points. This would happen with any gpx track I uploaded that was more than about 30-40km, no matter how I created it or transferred it to the watch. -
@MKPotts ah ok, I see. So it is not quite the same problem I’ve had.
-
So based on this thread
What is the suggested approach for a multi day activity? End and save the activity per day ? I assume the save would apply to s9p which I have.How can you merge the parts afterwards?
Also , if you don’t have coverage on your phone will you be able to process those saves ?Thanks

@thanasis you can sync activities with SA also if you don’t have internet connection.

Thanks @isazi , shall I assume that for the rest is as I mention?
so saving them (stop it ,save, synchronise) on a daily basis?but on the merging of the parts?
-
@thanasis
I wonder why you want to have one activity if a multi day activity is done on different days with dinner and sleep in between? Don’t get me wrong, everyone has his/her own process and philosophy.
personally I would record day by day and if you want to look at your entire track, load all relevant activities into quantified-self.io and merge them.living sideways
-
@freeheeler there is a difference between for example Moab 240 and Marathon Des Sables. Moab 240 - one activity, Marathon Des Sables - six activities
Btw, I’m far for competing in those races, just an example how I would like to have them stored -
@freeheeler I bet 200k in one go looks more impressive in SA than 4x50km haha.
But apart from that I think at such severe level of tiredness one may as well forget to finish/start an activity, so it’s more for a peace of mind I suppose.
