Our Story

In 2007 Martin Like had a mad idea to create a race in one of the most beautiful and dangerous environments on the planet. Shortly afterwards the 6633 was born!
Since that time, the team at 66 Adventure have been working tirelessly to deliver an ever evolving adventure to those brave enough to take it on.

Most of the race is based either on the Dempster Highway or on ice road. Depending on the edition and distance you can experience stunning hills or hypnotic flat ice. Every distance comes with its own challenges.

Anyone who decides to take part must understand that the race is an adventure, an expedition, it is subject to the environment which means there isn't one plan and there isn't just one route for the crew or the athletes! Be prepared to adapt!!

The 6633 is run primarily to feed the adventure need of the crew and the athletes. We do everything we can to make sure all our participants get the adventure and race they are looking for, whether it is the 120, 250 or 380 mile distances. We want as many people to finish as possible - but be prepared, not that many do. Just getting to the start line is an achievement in its own right.

We are blessed with an amazing choice of crew members including polar experienced medical professionals and accomplished ultra racers. Every year the crew work hard to make sure everyone stays safe (if not always comfortable!).

Athletes and crew can expect to experience temperatures as high as -5 or as low as -50 or more. It is an extreme environment, expect to be cold, train to be uncomfortable and prepare your mind for one of the toughest challenges you'll voluntarily commit to.

This is a self sufficient experience, that means you move, sleep and eat when you want to, its your race. We provide safety checkpoints with access to hot water and temporary respite from the environment. You sleep in the wilderness, camping along the route where you choose. You cannot sleep in the checkpoint vehicles or trailers, however, where a building is used for a checkpoint (e.g. school hall) you may use these spaces to sleep in.

Each race has a required completion time. Whilst there are no hard cut offs at the checkpoints, if you haven't got enough time to complete the distance then your race will be over. It is important to stay on top of your progress and know how far and how quick you need to move.
