2011 - Lawi ran, self-explanatory.
2012 - Besides the first 3-4 finishers, times were similar. Temperature was about the same that year.
2013 - A lot cooler and raining. BYU brought their best guys.
Having run both Pre-Nats last year at Lavern Gibson and the Griak in 2012, I would easily say that Minnesota is by far the much harder course.
