Wyoming State Meet course in Douglas. 5K record is not under 16:00, and despite what many think, the state has produced enough runners that one of them should have broken that barrier.
Also, Black Hills State's home course on the back nine at the Spearfish Country Club. 8K course record is 27 high, and they have some quality runners in the past. One must run a 535 yard par 5 uphill 3 times on the route.
