Powertap Question - How to train and race with one

Dumb question, but I’m not that familiar with these things.

How do you train and race with the powertap if you have training wheels and race wheels??

Since they’re about a grand, I’m assuming that most people don’t have a powetap hub on the racing wheels and training wheels?

Like I said, dumb question, but tell me what I’m missing please?

You have it built into an 808, race time you add a wheel cover.
