Quite simply the world's coldest and toughest ultra race.

Montane Yukon Arctic Ultra

Quite simply the world's coldest and toughest ultra. 430 miles of snow, ice, temperatures as low as -40°C and relentless wilderness, the YUA is an incredible undertaking.

The Montane® Yukon Arctic Ultra (MYAU) follows the Yukon Quest trail, the trail of the world's toughest Sled Dog Race. Where dog teams once slid and scrambled now human power chases up the trail.

Choose to race the 430 mile, 300 mile, 100 mile or marathon distance either by snow mountain bike, cross country ski or by foot. The race begins in Whitehorse, Yukon, finishing (for those that make it) 13 nights later on the in Dawson, Yukon. The marathon finishes just off the Takhini River. 

February 3rd - 16th 2019


The Montane Yukon Arctic Ultra will follow the Yukon Quest trail, the trail of the world's toughest Sled Dog Race.

The marathon finishes on Rivendell Farm just off the Takhini River. The 100 mile racers will go from Whitehorse to Braeburn. The 300 mile racers will keep on going all the way to Pelly Farm. There they will leave the river to turn around and go back to Pelly Crossing on the farm road. The 430 mile athletes will not return to Pelly Crossing. Instead they will continue on the Quest trail to Dawson City.

The trail will be marked. However, if there is fresh snow or a lot of wind it will be difficult to find the trail. If you want to enhance your ability to understand your orientation, we recommend you use a GPS. You can find necessary co-ordinates and more information on the race course:
