afaic, I can confirm that sync is faster, and I’m pleased they’ve sorted out the issue of the lock during an activity.
If I may make a suggestion, I’d like to see the climb guidance included in Run 2 as well, just as they were in Run 1.
Also, what I really miss about the Race S is that you can’t add a screen with an automatic lacp (only the manual one is available). I can’t explain why Suunto has omitted it!
