I'm going on an assumption that the 245 works the same as my 945. I have to go into settings for said activity, ie. running or cycling, and disable the lap key. Now I can press the back button to go to my watch face and use the up and down buttons to navigate my widgets. I press the back button again to return to my ongoing activity. Maybe it's the same with the 245?
To get information I can’t get from a data field. But it could be from the watch face as well, but I don’t seem to be able to access that during an activity either.
A sort of workaround: stop your activity and "Resume Later". Then you can get to the widgets from the clock screen as normal and when you're done, go back to your activity.
