Sounds like either you or she has some confidence issues that MUST be addressed. If she is stopping at 80cm at home, you can be sure she will at the show as well. You need to be completely confident and successful at home before you go and compete. It's not a matter of looking stupid or having her be silly. Stopping is a big issue and can turn into a HUGE and dangerous one if not take care of. The show is not the place for that.
If you're insistent on showing, is there a smaller class you can enter? It doesn't matter if she CAN do the 80cm, the point is she ISN'T (yes, even if it's just at first). If you must, I would suggest entering a smaller class as a confidence booster for the both of you.
