Yukon Quest 2016: Brent Sass arrives 1st at Dawson City

Alaskan musher Brent Sass, currently the leaderin the 2016 Yukon Quest, was the first toarrive at Dawson City at12:21p.m. local time.

Canada Border Services officers are on hand toscreen mushers as they arrivein Dawson after crossing into Yukon from Alaska. This is the first year that mushers haven't been pre-cleared to cross the border.

When Sass was asked if he had anything to declare, he replied "14 dogs."

Sass was first into Dawson for the third straight year, despite the facthisdogs were battling a stomach bug during the first half of the race.

Sass said it was a challenge keeping the dogs fed but they seem to have recovered.

"On the trail, other than what was coming out of their butts, they were really good," he said.

As the first musher to arrive at Dawson, Sass will win four ounces of gold if he completes the race.

Fellow veteran Quest musherAllen Moore arrived second at Dawson, abouttwohours after Sass.Hugh Neff, another veteran, arrivedabout 30 minutes after Moore.

Yukon's Ed Hopkins is the fastest Canadian, currently in fifth placeand expected to reachDawson lateWednesday night.

The teams set off from Fairbanks, Alaska, on Saturday. Sass is running nearly six hours ahead of the projected race pace.

"We've had really good trail in Alaska this year so it allowed [mushers] to pick up some time there," said race marshal Doug Grilliot.

"And over the last three to five years, the dog teams have just gotten faster."

Weather has also helped pick up the pace this year. It's been cool but not too cold, though Grilliot said the race could have used a bit more snow.

"The conditions have been as close to perfect as you can imagine."

Teams will take a mandatory 36-hour layover in Dawson City before beginning the second half of the 1,600 kilometre race to Whitehorse.

For mushers it's a chance to sleep while team handlers care for the dogs. Race veterinarians also examine thedogs.
