Do Fitness+ workouts end when a “Time to Walk” episode finishes?

I was listening to a Time to Walk episode today in Fitness+ that was 25 minutes long.

When I clicked play, the workout began and when the episode finished, I assumed the workout would keep going until I manually stopped it. I walked for about another 1/4 mile before realizing that the workout had ended and stopped recording data.

Is this supposed to happen?

Is there a setting to keep the workout running despite the episode ending?

I love this feature of Fitness+, but if my walk is longer than an episode, I don’t want to lose activity data because of it.
