There are many events that could lay claim to the title of most extreme driving challenge in the world, but only one takes competitors to the shore of the Arctic Ocean in the dead of winter.

"It's the great, big, broad land 'way up yonder,
It's the forests where silence has lease;
It's the beauty that thrills me with wonder,
It's the stillness that fills me with peace."
- From "The Spell of the Yukon" by Robert W. Service

The Alcan 5000 Winter Rally runs once every four years, and has developed a devoted following among adventure-seekers from all over the world. This year, 40 teams made the long drive north from Seattle, Washington to Tuktoyaktuk, Northwest Territories.

The Alcan rally first dares teams to make it to the far north. Tuktoyaktuk lies about 300 miles north of the Arctic Circle. In the short summers, residents fish the Arctic Ocean. The rest of the time they survive winter temperatures that hover around 40 degrees below zero.

The second part of the competition is a daily Time-Speed-Distance test that challenges teams to drive a challenging road at a precise average speed. It's not a race, but rather a demonstration of the ability to arrive exactly on time.

Teams may enter virtually any kind of vehicle they choose. This year's entrants ranged from a 1973 Ford Capri to a Japanese-market right-hand-drive Mitsubishi Pajero and a brand new 2020 GMC Sierra AT4. (The GMC was this writer's ride on the rally.) Subaru cars and SUVs are a popular choice, as are 4WD pickup trucks. Entries are divided into classes based on the type of vehicle - 2WD and Historic vehicles get their own classes.

The rally sets off from Seattle and crosses the Canadian border on the first day. Most people don't realize that British Columbia is about the same size as California. B.C. is known for wildlife, and this is where travelers will usually see American Bison, Bighorn Sheep, Moose, and Caribou. In winter, it takes nearly three days to climb through B.C. and reach the Yukon Territory, where the adventure really begins.

Adventuring in the Arctic

As we arrived in Whitehorse, temperatures fell below zero. The fat snowflakes of a picturesque winter give way to hard ice and the trees get smaller as teams drive north through Canada's gold country. The last night before the hard push to the Arctic is spent in Dawson. This town dates from the Yukon gold rush, and the frontier spirit lingers there in saloons and rustic hotels.

From Dawson, the rally turns off on the Dempster Highway. This is the only road to Inuvik and the Northwest Territories. The next settlement is Eagle Plains, about 250 miles from Dawson and just 20 miles from the Arctic Circle. Teams stop at the circle monument for photos and bit of clowning around.

Driving becomes serious business on the Dempster. It's a gravel road in summertime, but in the winter it's packed snow and ice, with snow drifts along the shoulders that are easily capable of swallowing a car. About 50 miles in, several teams opted to turn back and wait in Whitehorse for the rally to return.

The teams that elected to go on traveled in groups and kept in touch by radio to ensure that no one was left stranded, and several vehicles had to be pulled out of trouble. Temperatures on this year's rally plunged to -20F as we crossed the Richardson mountain range and entered the Northwest Territories. At this point teams are not competitors. They're partners in getting everyone over the top safely.

Modern Tech to the Rescue

As we went along, our GMC showed the value of modern technology. The AT4 package includes a raised suspension, skid plates to protect the underside of the truck, and an Automatic mode in the four-wheel-drive system. Many 4X4 vehicles turn off the traction and stability control systems when 4WD is engaged. The GMC's automatic mode allows the truck to function like an all-wheel-drive SUV, sending power to any wheel that has grip while maintaining traction and stability. The effect was exactly what we needed to stay on the road.

We chose Nokian Hakkapeliitta LT3 studded winter tires for the journey. The triangular studs in the Nokian tires bite into the ice, while the advanced tread design molds around snow and frost to grab traction. As wise Arctic travelers recommend, we carried two spares. However, the Nokians survived everything we threw their way and we never used the emergency tires.

It's worth mentioning GMC's extensive camera system. The Sierra has forward and rear-facing cameras, and can deliver a birds-eye view around the truck for tight maneuvering. Best of all, the rear-view mirror is also camera based, with an eye mounted on the back of the cab. In the Arctic, the rear window of any vehicle tends to collect a thick coat of frost and ice. The GMC camera offers clear wide-angle view to the rear that also includes most of the blind spots.

FInally, our GMC was equipped with the new 3.0-liter Duramax turbo-diesel engine. With 477 pound-feet of torque, this smaller six-cylinder pulls like a V8. It's paired with a 10-speed automatic transmission to maximize fuel economy. We saw up to 30 MPG in warmer climates to the south. In the Arctic, the extreme cold hits everyone's fuel economy, but where gas engines were averaging under 15 MPG, the Duramax returned about 18 MPG.

The Spell of the Arctic

After a long day of hard driving the rally reaches Inuvik, NWT. At about 3,250 people, Inuvik is the largest town north of the Arctic Circle in North America. Here temperatures plunged to 40 below zero, but at this point no one is going to give up on the great goal. In the morning, teams rise before dawn and continue about 100 miles farther north to Tuktoyaktuk, celebrating the sunrise on the beach of the Arctic Ocean. Or rather, we take the locals' word for it, because there's nothing but ice as far as can be seen.

Tuk is the end of all roads. From here it's just 1,500 miles to the North Pole, all ice. Only Barrow, Alaska is a bit farther north and still reachable by car. After some photos and a little celebration, the Alcan teams turn away from the rising sun and start heading home. The adventure's not over yet, however. There are still five more days of competition before the rally ends in Anchorage, Alaska.

On the way back down, there's more time to pause and appreciate the scenery. The Arctic is wild and very much untamed. Teams observed foxes, wolves, and even a very quick Arctic hare. We were forced to make an unplanned overnight stop in the tiny village of Fort McPherson when the pass over the Richardson mountains was closed due to a blizzard. Teams pooled their food and made a potluck dinner as the local church opened its doors and broke out the supply of cots they keep on hand for these occasions.

At the end of the event in Anchorage, the team of Garth Ankeny and Russ Kraushaar in the vintage Capri won the competitive portion of the rally. By that point, everyone's ready to cheer because after driving 5,000 miles to the top of the world, just being there feels like a victory. That's why people return to the Alcan Rally again and again.

"There are hardships that nobody reckons;
There are valleys unpeopled and still;
There's a land— oh, it beckons and beckons,
And I want to go back— and I will."
