How do you delete a workout once you have created it using the "custom" feature?

I'm new and an old goat, have patience on me.

I have iPod nano, have created several workouts by:

1. Oh home screen, tapped Fitness
2. Tapped Run, then tapped Distance
3. Tapped Custom
4. I set the distance to 7 miles
5. I choose my playlist of the 50"s and 60"s music
6. Then I tapped Start workout
7. I tells me to move and it works just fine.

The manual tells you how to use a saved workout.

The manual does not tell me how to select a saved workout and delete it so I can do clean up work.

Does anyone know the process to delete a selected workout and leave the rest. I have gone through the owners manual, and I cannot find anything that gives you the process to delete a single workout.

If you know, I would appreciate the step process starting from looking at your iPod nano.

Thank you,

Otto
