Maximum activity duration (storage space)

freeheeler

@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?

DMytro

@freeheeler I suppose garmins that can store 16GB of music certainly can store 200h race.

sartoric

@DMytro
well, maybe, if storage space is shared

DMytro

@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.

DMytro

@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?

freeheeler

@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.

Likarnik

@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

DMytro

@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.

isazi

@thanasis you would need to export the FIT files and stitch them together somewhere else, then import them back in SA.

Likarnik

@isazi and lose data by design

@Likarnik
I am aware for this topic for races. But when I go on a skitour for multiple days and it is not a race, personally I don’t see a reason why multiple days should be one activity… maybe what @DMytro says
I know people who record the commute there and back in one activity… but in between there is 10h of being at work again: philosophy question

isazi

@freeheeler I am with you here. If I wanted to do a race of this kind, I would like to have a single activity. But my usual multi-day activity is climbing/hiking/mountaineering and I consider it a collection of daily activities, because I eat and sleep in between

Likarnik

@isazi @freeheeler I agree with you on multi day trips, but as far as I understand, @MKPotts is talking about races

@freeheeler philosophy question? Maybe we should include ski touring/backcountry skiing/skimo in here
