I am having a problem registering an HIIT session which takes 40 sec intervals and 20 sec rest. I can in the custom setting enter 40 seconds but the timer starts running at 60minutes instead of 40 seconds. I run version 9.37

Please post a screenshot of your training/workout.

For the custom it shows minutes:seconds for interval and rest. There is no hour option (only 60 minutes).

So set the first digit at 0, second at 40 for the interval. Then for the rest set 0, then 20.

That is exactly what i do set the minutes to 0 and the seconds to 40 but still the countdown starts at 59:59.

Hence the question if you could post a screenshot of the training/workout. Much easier to understand what the potential issue could be.

First photo is setting the interval custom to 40 sec, then rest interval to 20 sec, then starting the session shows the timer starting at 59:59 sec.

I've just tried to configure a workout like yours(as I haven't had any problem till now with HIIT timers) and it works fine.

I'm on beta 10.39 so the problem, if exists on 9.37 is solved now...at least in my case.

I configured a HIIT workout like you did. No issues whatsoever. I'm on beta 10.39.

Another idea: you could try to setup the training in Garmin Connect (App or Web) and synch it to the watch. Maybe that will do the trick?

I am on 9.37 and had no issues setting it up to 40s and 20s
