Yukon Arctic Ultra competitors wary of cold-weather risks heading into Sunday's race

The temperature in Whitehorsehas dipped, just as competitors are doing final preparations for the Yukon Arctic Ultra this Sunday.

Environment Canada is forecasting a high of -25 C over the weekend.

The 82 participants in this year's race should be well aware of the dangers posed by the frigid weather after last year's serious injuries. Race distances range from marathon up toalmost 700 kilometres for those travelling the entire distance between Whitehorse and Dawson City. They may travel on foot, skis, or bike.

• Yukon Arctic Ultra racer may lose hands, feet to frostbite

• Another Yukon Arctic Ultra racer faces amputations due to frostbite

Last year, two participants underwent amputations due to serious frostbite. In the most severe case, Italian competitor RobertoZandahas both his legs amputated at the shin. His right hand was also amputated, and most of the left.

'My hands are my life'

The fate of Zanda weighs heavy for competitors like Russ Reinbolt, who says he is "singularly focused" on avoiding frostbite.

"My hands are my life," said the ERdoctor from Southern California.

Reinbolt, who is racing 480-kilometres to Pelly Crossing,has experience competing in the cold, having previously run a 160-kilometre race in Alaska.

"I've got like six different combinations of mittens and gloves because I just can't afford to get frostbite."

Conditions could be challenging

Race competitors have been doing mandatory gear and safety checks this week. All competitors doing distances greater than a marathon must carry items including fire starter, a sleeping shelter and 48 hours worth of food provisions. Gear is normally pulled behind competitors in a sled.

On Wednesday night, they went on a four-hour evening hike to test gear and set up their camping gear.

Shelley Gellatly, a local guide who is also competing this year, led the way. She plans on doing the full distance to Dawson City. Pre-race, she is wary of the conditions.

"For me personally, this wet heavy snow I find in some ways more challenging than the colder weather because it's really tough to stay dry."

New safety measures

Race founder RobertPollhammersaid some people wereturned down from entering the competition this year because of new entry requirements.

For the first time, each potential competitor was interviewed by phone, during which time Pollhammersaid he discussedthe risks.

"I amliterally tellingpeoplethey can die out there," he told the CBC in January from his home in Germany. "This is not some joke or funny adventure. This is serious business when it gets that cold."

Pollhammersaid the race organizers will make it as safe as possible but that "there is no 100per centsafety."

Now in Whitehorse, Pollhammer said a couple of people didn't make the cut.

"We had to screen out a couple of people for language reasons, because they do need to understand the briefings. And we had one person who didn't have the time to do a training course before. All the people who don't have cold weather experience need to do a training course."

Yukon competitors

While the race attracts a mostly international crowed, there are a few Yukoners competing. They include:

• 160 kilometre race: Matt Hosford of Mayo and David Brabec of Whitehorse
• 480 kilometre race: No locals
• 688 kilometre race:Jessie Thomson-Gladish, Shelley Gellatlyand Gillian Smith of Whitehorse.

There are also several Yukoners competing in the marathon distance, which ends at Rivendale Farm.

The Yukon Arctic Ultra starts Sunday at Shipyards Park in downtown Whitehorse.
