One big loop, starting by the ICLE building entrance to the Big House and ending through the tunnel onto the field. The only hill I remember was going downhill on State Street on the way back to the stadium. It was a quick fun run (but I did the 5k), and ending up at the 50 yd line was awesome. I believe the 10k just takes a larger loop and starts earlier.
