I thought this name sounded familiar. His actual name is Holbrook Call (although in all the results from high school it is listed as Call Holbrook, so I always thought that was his name). He ran at Star Valley HS in Wyoming Class 3A, the second biggest class and graduated in 1995.
For all his "easy" wins in HS, he only the 1600 and 3200 his senior year. The 3200 was easy, winning by 20+ seconds, but his 1600 was by 1 second. Oh, and no XC titles. Although, I think SVHS did not have XC since they were more concerned about only FB.
Never remember hearing anything about him in college, and I definitely would have noticed if a Wyoming native had run sub-4:00 in the mile. I would love to see proof, as long it is not on a downhill road course.
He was a tough runner, but nothing great, even by Wyoming standards.
