I would agree with the post about running at altitude and then dropping some crazy time at sea level. If you live and train at altitude and have little time to do any fast training at sea level as most Big Sky Conf guys don't, more than likely you will run the same times that you have always run. I also think that people make too big of a deal about running with or without great competition. If you look historically at meet results the mile more than likely will be like every other championship meet. Almost every coach will tell their runner to run with the pack and look to be in position over the last 400-600 meters. Times from banked tracks, flat tracks, oversized tracks, sea level, the moon, or wherever it really doesn't matter that much. If an athlete has put up consistent times over the year and is healthy they have a legit shot at doing well.
The winner will probably run 4:01-4:02 in prelims (2:04, 1:58ish splits) and then come back in the finals with a 3:59-4:01 (3:32, with a 27ish last 200m). Even the best milers in the past have had a really hard time breaking 4:00 in the final.
That is exactly why anyone can win on Saturday!
