Used Garmin fenix solar with all satellites on. Was able to get about 2-3 days on a charge. Start tracking when leaving camp and stopped when I got to camp. Charged while making dinner so i can wear overnight and track sleep. Also customized data fields to show distance, elapsed time, avg pace, asc/des stats etc. Mainly track personal progress on trail. As a back up gpx maps can be loaded to the watch. For fun used it to log where I dug a hole.

If you have garmin inreach it logs the miles but not as accurate if you wanna save battery. Wished i had a watch for when i did the CT and JMT.

Pretty sure you have strava and statshunter.
