Need advice for a good GPS watch with SOS

[amishfarmer]

So I'm currently venturing into 2 areas that having a GPS device would be helpful.
I'm currently training for a 24hr ultramarathon and wanting to get out and hike more. The hiking may be just me out and about and I always want a backup plan in case something unforseen (injury, animal attack etc etc).
So what I'm looking for is a watch with an GPS sos function that has a battery life that lasts more than say 30hrs or so. Basically a watch I can use for training and ultramarathons as well as hiking to use as a emergency device in case I get into trouble outside of cell service.
I've done some searching but having a hard time finding one that meets both my needs. This saves me buying a watch for running and a seperate device for hiking.
Thanks guys and Gals

The only watch that has the juice for Ultras is the Garmin 9XX series. Even then it only last 20 hours so you have to charge it while you're running (it can still record while charging).

For the event itself you stage the battery and a USB cable in a drop bag at the appropriate aid station.

You don't want your GPS watch to also be your SOS/PLB/Sat Com device. That's a single point of failure. When I hike, I use my 920 for hiking stats, a handheld 30X for location checks, especially in the winter when the trails are buried, and an Inreach Mini for getting help if outside of cell range.

After I test it, my Inreach remains off the entire time I'm hiking. It has one purpose, to get help. Although I've been thinking of turning tracking on so my wife will see if I haven't moved in a while which could mean I am injured and immobile.

You bring up a good point that I hadnt thought of. The inreach isnt rediculous prices and worth the piece of mind. My long time good friend and experienced ultra got me looking at the garmin fenix 5x plus. With the battery saver the GPS is supposed to work for 30 hours. So I'm going to consider 2 devices now.
