I used my first Garmin watch (645M) from about 2020 to 2024. I gave that one away to a friend and bought a new one (965) to replace it. I seem to have lost all of my activity history with my first watch. (TBH, I never really paid attention to see if I could see it for some time before it disappeared...But it is gone now!) How can I get that back? It has my first marathon and all of the training involved and I wanted to go over that history!
(If I go to my PR page, my older PR activities are still accessible and show that they are attached to the 645. So, I can at least reminisce about some of my PRs! :-)
