I just ordered a Polar M200 wearable. $134.90 @ Merlin.
It is a basic GPS (breadcrumb) running watch with a bunch of social media and phone "lifestyle" integration I'll never use. The built-in optical HR is interesting but if it isn't accurate then I'll just run with a chest strap like I always have. Already using a Polar V650 on the bike and keeping running and cycling on the same platform is important to me. Really just need heart rate. Elevation change, temperature and GPS track are bonuses.
That being said, I'd still like to eyeball one of these Fenix 5's, especially the maps, and will have to think about getting one if the maps are legible.
