Krupicka grew up near Niobrara, Nebraska. He used to be a graduate student at the University of Colorado, but dropped out to be a professional runner. Krupicka earned his BA from Colorado College in 2005, double-majoring in physics and philosophy. In 2006, he completed a second BA at Colorado College in geology.
