Commencing 12th March 2010
From Eagle Plains, Yukon to the banks of the Arctic Ocean at Tuktoyaktuk

A true Arctic experience - this race really does enter the Arctic Circle and can quite genuinely claim to be the Toughest, Coldest, Windiest Extreme Ultra Marathon on the planet.

This race is only for big boys and girls unless you’re mad!!!!

See Application section for entry details.

Race Structure

The 6633 ultra is a non stop self sufficient race over a distance of either 120 miles or 350 miles. Both races cross the line of the Arctic Circle, with the longer race continuing to the banks of the Arctic Ocean at Tuktoyaktuk. For 2010 only runners will be eligible to enter the race, albeit Cyclists will be able to take part on a "journey" basis subject to conditions that need to be discussed with the race organiser prior to entering.

Competitors will be expected to carry or pull on sleds all their provisions for the race including food, cooking items, clothing, sleeping kit and other safety gear. Racers going all the way to Tuktoyaktuk will be allowed 2 drop bags for limited essential gear at approx 120 miles (Fort McPherson) and 230 miles (Inuvik). All racers will be allowed to have a bag at the finish line for spare warm clothing etc.

Checkpoints will be spaced along the route at between 26 and 70 miles apart, where racers will be able to rest for a while and be able to prepare their own food. Hot water and Shelter are the only things guaranteed at the checkpoints.

The race is once again being organised by Martin and Sue Like together with significant help from a multitude of individuals from the UK and more importantly in Canada. Both Martin and Sue have raced in Arctic conditions on a number of occasions and it is this experience that they will be bringing to the 6633 ultra to make it the most testing, rewarding memorable race that any self respecting ultra racer will ever do.
