Runbuk, Inc.

How far can you run, how far can you push yourself, how far away to earth’s extremes are you prepared to travel?

Runbuk has been delivering world class running experiences in the most challenging and remote locations on the planet, whether it's the world's northernmost marathon, the world's southernmost marathon, the world's highest desert marathon, or the ultimate World Marathon Challenge.

We organize the World’s Coolest Marathon ®, the North Pole Marathon ®, where you can become one of a truly select few to race at the top of the world - at the Geographic North Pole. In this location, you can feel on top of the world if you manage to overcome the intense sub-zero temperatures to finish 26.2 miles at one of earth's farthest extremes.

The Antarctic Ice Marathon ® at the opposite end of the planet is also organized by Runbuk, providing competitors with underfoot conditions of snow and ice throughout, an average wind chill temperature of -20C, and the possibility of strong Katabatic winds on the frozen continent.

The amazing World Marathon Challenge ® allows competitors to push themselves to the limit in both individual and team competitions. The first marathon of this ‘7 Marathons 7 Continents 7 Days’ trip begins at Novo (Antarctica) and is followed by marathons on consecutive day in Cape Town (Africa), Perth (Australia), Dubai (Asia), Madrid (Europe), Fortaleza (South America) and Miami (North America), all conducted within 168 hours from start to finish.
