”Running is the simplest, most elemental form of movement in the mountains. I run to keep me connected to my surroundings."



Anton Krupicka is a mountain athlete living in Boulder, CO. In addition to ultramarathon racing, Krupicka is also an avid climber and skier. His ideal outdoor objective combines running, climbing and biking to explore the mountains in a self-supported, human-powered adventure. "Explicit or not, I have always derived my motivation in the outdoors from curiosity and connection. Even before I started running as a daily discipline in February 1995 (I have the training logs to prove it), I dutifully conducted extensive exploration of the ridges and ravines on my family’s 640-acre farm above the Missouri River in northeastern Nebraska—I was continually building huts, blazing woodland paths, and hunting for fossils. My parents encouraged such behavior by modeling a lifestyle that emphasized a pragmatic appreciation for and connection to the natural world, which most auspiciously presented itself in the form of a now almost old-fashioned rural self-reliance. For me, this ethic was first projected beyond our Nebraska homestead during annual summer camping and hiking trips to the American West’s National Parks."



1) Which is your favorite place for running?
My favorite place to run is above treeline in Colorado in the summer.
2) Which is your specialization?
Steep and technical ultramarathons (80K and over). Combining running and technical scrambling.
3) Do you have a pre-race routine?
Before I race I try to keep everything as normal and routine as possible. A race is just another long run in the mountains.
4) When and why did you start running?
I started running in 1995. I was preparing for a 1 mile time trial in gym class.
5) Which are your La Sportiva favorite shoes?
The Mutant is my all-time favorite!
6) What's in the air?
Over the next couple of years I hope to combine running with both biking and climbing to facilitate interesting multi-sport adventures. Additionally, I am excited to stay healthy and return to ultra races after many years of injury.
