I think people are making too big of a deal about this. She is running a 2 mile race. Whether it is against pros or not is not going to hurt her. Say she ran this same race but it was against high school competition. She would crush the field and not get any experience out of it. Now if she races against pros she will actually be able to run against people at her level. Believe it or not either way it is still 8 laps and 18 meters of hard running. I think she will be fine running in races of this level even if she is young.
