Apple Watch - Screwy during running

My Apple Watch, just purchased in December, is not working well. When I go on long runs, I sent the Workout to run before I start. When I stop the visual is magnified and will not let me get to the workout to either see where I am (time and distance), and to swipe to turn it off. Just today it also showed that my battery was drained. I managed to get to the off/done screens, then I turned it off completely. When restarting it is still not ok. It looks like the workout was not recorded. This weirdness during/after runs 5 miles or longer have happened repeatedly. Any ideas?
