Fifteen-year-old Cooper Lutkenhaus just booked his position in the 800m final at USATF Nationals. He dashed under 1:50 last season, two meets earlier. His father trains him now. The father coaches at Nebraska-Kearney as coaching his son at meets in New York lately. Lutkenhaus holds cool in races in spite of the jump up ranks. Scouts now monitor his steady times and steady focus as he chases advanced tracks.
