Trail Running Shoes

I have a race tomorrow afternoon, would there really much difference if I wore racing flats instead of trail running shoes? flow paths where i are not too crazy, if anything a little muddy when wet, but the weather does not seem to be looking bad tomorrow, but I know that distance runners during wear their racing flats because they are lighter then it really would be a bad idea if I landing hiking boots this time?

The choice would probably be less painful than what you are accustomed to trail running in.
