In reviewing/compiling XC results (boys' sub-15 / girls sub-18) from past Kinney/Foot Locker nationals and midwest championships, it has opened my eyes into just how rare it is for boys to go sub-15 and for girls to go sub-17. I hadn't realized how rare that is until now. While courses differ, especially given conditions, it does give you an appreciation of just how difficult it is, and just how impressive those performances are. CJ Robinson's 16:40.4 win in 1981, while definitely on a flat, fast course, is still damned impressive 41 years later!
