Why aren't there any night cross country races? They have night track and road races. I always prefer racing at night and it always seems more exciting. I don't think it would be hard to setup. You can get those mobile construction lights to light up the open parts of the course and use lights on the ground to mark the edges of the trails. I think it would be a lot fun.
Indiana State should setup lights on their course, it would be easy because of how open it would be. Then they can host NCAA's at night when it is more calm out.
I have raced in deep fog for cross country once, couldn't see past 50m. That was cool.
