The 2018 edition of the 6633 Arctic Ultra is going to be special.
As one of the most respected extreme ultra marathons, the 6633 Arctic Ultra is regarded by many as the toughest, coldest, windiest ultra distance footrace on the planet.
The 2018 event will be the 10th edition of the race.
The non-stop self-sufficient foot race is over a distance of either 120 miles or 350 miles, with both races crossing the line of the Arctic Circle.
The 120 mile race finishes at the First Nations Hamlet of Fort McPherson, whilst the longer 350 mile race continues to the banks of the Arctic Ocean at Tuktoyaktuk.
