If after following these steps the application fails to install on your watch, please try restarting your iPhone and Watch and repeating the process.

After you have completed a run your workout activity will automatically be stored on in Apple Health. You can view your workouts on the Apple "Fitness" app on your iPhone.
For each run, an Outdoor Run workout will be visible with details such as time, distance heart rate and map (if you granted location permissions to the Watch App). If you have the warmup and cooldown walks enabled on the app a separate Outdoor Walk workout will be recorded for each.

Warmup and cooldown activities are recorded as separate entries as they are unlikely to change as your progress through the program. The actual main program is recorded as one single run workout entry which includes all the run and walk segments.

As you progress through the program you start doing more and more run segments and towards the end of the program sessions just consist of running. By keeping the warmup and cooldown separate you can easily compare your progress over time and look at your distance, average speed and heart rate (without the warmup and cooldown walks skewing the data).

Make sure you do not have any other health/activity app running on the watch when you use Watch To 5K. The watch can only have one fitness application running at once.
WatchTo5K will automatically record and store relevant workout activity while you run. This data will contribute to your Apple fitness rings.

Please confirm that permissions have been granted to the application. To check this on your watch go to
Settings > Health > Apps > Watch to 5K. On this screen ensure all the toggles are on (green).
