Practical limits to activity time/duration/length

Hello, next month I will be doing a ultra distance paddle race, 1000ish miles spread over 6-10 days. It consists of 18 paddle hours and 6 mandatory rest hours, per day. My watch is a Fenix 7X SS.

Are there any practical limitations to how long a SUP activity can be? All in its probably going to take 110-140 hours. I'm thinking in terms of how large/number of points a FIT or GPX file can handle before something might crash or get corrupted. I would really hate to get 3 days in and lose the whole thing.

I could end the activity and start a new one each day, but I was planning on just pause/resuming around the breaks to have it all as one activity.

One thing I have noticed after uploading the planned race course to Garmin Connect, it really gets sluggish and slows down my web browser a lot, given the sheer size of the track. Doubly so when Course Points are selected. And that's with a fraction of the number of waypoints compared to a watch recording once a second.

I have already run into the problem of being limited to 200 course points per course. I've played around with trying to split it up into 4-5 chunks but so far its been a pain in the ass to do, and no software out there (Basecamp!) is user friendly enough for me to handle it.

The longest continues activity I have recorded in one shot it ~15 hours and it handled it fine.

    Perceived effort was zone 2 for most of the race. Some pieces higher or lower.

    River was definitely flying on the second day above Carmacks to Dawson. I think we covered 188 miles in the longest day. After Circle and the last 2 days it dropped considerably.

    Ah, pulse ox, right. Disabling it really adds to the battery life.

    However, anyway, it's strange how it only consumed %10 in 16 hours. Solar seems to have helped a lot.

    Definitely solar supercharged :) 4-500k+ daily lux really is outlier type conditions. Hard to replicate that in areas without 22 hours of daylight

    At this moment Im frustrated cos I went surfski paddling today and forgot my chest strap. 

    Fenix 7 optical HR is working terribly for me when paddling. I don't if it's due to the watch weight, water influence, strong sunlight or whatever. 

    When I paddle harder, feeling like 140 bpm, the watch keeps showing like 106 bpm even after like 10 min like this (not only a quick sprint). 

    I wear the original silicone strap firm enough. More would mark my wirst and prejudice the blood flow while paddling, not good idea.

    My former FR 745 was not so inaccurate as this F7. Maybe cos it was lighter? Maybe gen3 OHR sensor was better at this environment? 

    About the long activity, last week I did a not too long SUP activity, like 2 or 3h, but paused and resumed a couple times. Was also using IQ datafield "stroke index". I don't know why, but that activity never synced up to GC, even trying to do it manually it says the fit file has some problem.

    I've had issues with the Vivoactive 3 Music OHR as well. It just doesnt seem to be a very accurate technology doing any kind of upper body exercise.
