Cooper Lutkenhaus Debuts at Prefontaine Classic with Poise

Cooper Lutkenhaus, 17, makes Prefontaine Classic 800 debut with veteran's poise and youthful energy

Lutkenhaus is not only breaking age marks — he's the 18-and-under world record holder — but is beating the best of the best, too. Down the road, Lutkenhaus could be the one who eclipses David Rudisha's long-standing world record — a mark that's near the age (14 years) of Lutkenhaus. Because Lutkenhaus doesn't really focus on times or medals when he takes the starting line.
