There is no standard course throughout the country for high schoolers. (warning: incoming generalization) Runners in the northeast see a lot of hills on their courses; runners in the south see a lot of flat/fast courses. How would a flat/fast course be similar to district/region/state/regional championship courses in the Northeast? and how would a hilly course be similar to district/region/state/regional championship courses in the south? Yes, Portland Meadows is a loop course, and yes it does have hay bails and man-made "whoop-de-doos" that make it more "european"... but so what? is that really a detriment to runners in the field??? No, it may make it less like a grass track but it doesn't do much beyond that.
Yes, some years it is muddy, but some years it is not, and I can understand runners who are afraid to compete in the mud not wanting to compete at NXN.
But, again, I disagree that the course ONLY tells us "who is the best mudder" ... Runner A can be a better mudder than Runner B, but if Runner B was a significantly better runner they should still come out on top... individual strengths and weaknesses, unless severe, are only going to affect those of similar talent. Who is to say that a runner who would win on Course A is any worse than a runner who would win on Course B? Every runner has their strength and weaknesses... someone is going to have an advantage no matter where the race is run (though I agree that in 2005, 2006, and 2010 that advantage was a bit exaggerated at NXN).
