26.2 + Apple Watch Ultra Workouts

Did you create a custom workout for your runs, and if so, does your watch also do that when you are recording a normal run, using the default Outdoor Run or Outdoor Walk as a workout?

Or do you just record one run, end the recording and start another run right after that?

Did you already try to force restart your iPhone and Apple Watch after the latest updates which came out yesterday?

Force restart iPhone - Apple Support

To force restart your watch, press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again.

I can start workouts for my Apple Watch Ultra 2 from the Fitness App on my iPhone or directly on the watch without any problems, running iOS 26.2 and watchOS 26.2
