Ahh yes, the far superior watch that requires you to run flat ground in order for a bunch of its metrics to work.
I bought a COROS a little over a year ago. Initially it provided some nice metrics such as vo2max etc... from my trail runs. Then suddenly a few months after use an update came out which reset all those metrics and gave me a message saying I needed to log road runs for 7 days straight for it to measure those metrics it had already been measuring based on trail runs. The watch being marketed as a mountain sports watch with exceptionally long battery life. What a joke. I have a Garmin fenix now and unsurprisingly it DOES NOT require me to completely change my training and run roads in order to produce these metrics.
PS COROS watch faces look like they were created by a little kid. Enjoy your piece of crap toy with long battery.
