Canada's cross-country and biathlon world cup athletes are getting a head start to the training season in Canmore – thanks to Frozen Thunder. 

It's a unique ski trail, made from last year's snow that was stored through the summer under a thick layer of sawdust.

The track was modeled after similar ones in Europe, but it's the only one of its kind in North America.

Frozen Thunder was first created in 2009. 

At that time it was about 400 metres long, but after adding more snow every year, it’s now two kilometres long.

Athletes say the early start to the season gives them a big advantage.

"Having the snow out where is a huge benefit for us, staying at home and getting on snow early where we use to have to chase that, one of our areas was Finland before…Finland this time of year is not that much fun," said Robin Mckeever, a coach for the Canadian Paralympic cross-country ski team.

This year, Frozen Thunder will host its first early season race. 

More than 100 nordic athletes from Canada and the U.S. will compete in Canmore, on October 26th.
