Just as the title says, curious how well this watch performs on a treadmill?
I currently use a Suunto Baro 9, and it is consistently more than 20% off on mileage when running on the treadmill, which then effects paces, zones, etc. I have tried using my Stryd Power meter with the watch while on the TM, and while the power comes across properly, the watch defaults to its sensors for speed, mileage, etc..
I have used Garmin products before (Fenix, Fenix 3, and FR735XT) all with varied success (Both Fenix Series watches GPS was HORRIBLE outside), but always came back to Suunto. Now, with the problems they have with their apps, and the change in running (treadmill vs outside running ratio), I think it might be time to get back into a Garmin..
