No worries at all, yeah I can understand.
I'm a fairly short person, so for it to register an outdoor walk to count towards the exercise goal, I need to be close to running.
I sort of gave up trying to make it work and accepted it doesn't work for my walking speed. I kind of like thinking going for an outdoor walk is like Mixed Cardio.
You can choose other as a workout and then there are plenty of different types of activities to choose from.
I spent a month trying to make the Outdoor Walk work for me. It's frustrating because you are exercising but the watch software isn't programmed to pick it up, I guess so it doesn't count walking in general as exercise. Hopefully, it is something that changes with future updates or sensors. But for now and our sanity - Mixed cardio?
