I just signed up for a 50k trail race and dug out my old Garmin Forerunner 15 for some time/distance/pace monitoring. For whatever reasons and despite trying many fixes, I can’t get it to sync with my computer (it will charge and update, but won’t provide data back to my computer dashboard – and it can’t connect with my phone — no bluetooth). Thus, given its age and approaching holiday sales, I figure it is probably time to get a new Garmin watch to help with training.
The number of options is amazing, but I am pretty overwhelmed. I don’t think I need anything fancy, the main things are just heart rate monitoring (with a chest strap or from wrist) and run data. I don’t need the ability to check my phone messages, play music, text my friends, etc. But since I am often backpacking, climbing, hiking, trail running, etc. the map features of the Fenix are tempting. On the other hand, I already have an In-Reach mini I take with me, so maybe just the most basic is best (like a Forerunner). Battery life is probably important, I would like to try some longer races at some point and since I am slow that would likely be heading toward 20 or 24 hours. The Instinct looks nice and rugged, but doesn’t seem to be discussed much.
I guess what I am figuring out is that I don’t know enough to even know what to consider. Some options would be: basic Forerunner 55 for under $200, Instinct (non-solar) for $160, or just invest in a Fenix 6 ($400) – I am sure I would learn to love and use all of its features.
Thoughts? Things to consider? Anything else?
