UltraTrac on my Fenix 5 is pretty useless though, you may as well not be recording at all at that point. I'm not sure if it's gotten better on the more recent watches, but the reported mileage would be off by 30%+ and the resulting map wouldn't even come close to resembling my actual path.

That said, even in normal GPS only mode (no Gallileo/GLONASS), the 5 when it was new would get 30 hours of recording. Enough for most ultras, 3 days of backpacking if you record 8 hours/day, and also enough for a week trip with an hour of running every day.

I had an older Fenix and the distance accuracy was pretty bad. But no one seems to have an issue with the current ones.
