DO YOU HAVE WHAT IT TAKES?

In 2007, the legendary 6633 Arctic Ultra was born with the launch of the 6633 Classic 380, a race that pushed the limits of human endurance in one of the harshest environments on Earth. Over the years, this iconic race expanded with new challenges and now with the creation of 66 Adventure, we’re on a mission to challenge, inspire, and empower adventurers to go beyond the limits of the ordinary.
