"Riding the Tatshenshini" chronicles the breathtaking journey of four generations of freeride mountain bikers in search of the ultimate ride. The 42-minute Red Bull TV documentary follows ‘The Godfather of Freeride' Wade Simmons, Darren Berrecloth, slopestyle pioneer Tyler McCaul and Carson Storch as they set out on an unforgettable two-week adventure through Canada’s northern wilderness in search of the country’s most impressive untapped terrain.

The Tatshenshini-Alsek Provincial Park contains nearly 1 million hectares of glacier-covered mountains and pure untamed wilderness. Rafting through icy glaciers and unpredictable weather patterns proved challenging for the team.

“It’s a very demanding environment,” the group’s guide warned the team. "The Tatshenshini is relentless. The Tatshenshini has claimed lives. It’s a foreboding place for people if you’re not prepared."

The expedition began in Yukon’s Dalton Post and follows the foursome 260 kilometers by raft to the incredible landscapes of Dry Bay in Alaska, home to the world’s largest non-polar ice cap and the most active glaciers on the planet.

“In order to really develop your skills, freeride mountain bikers need to constantly explore and mine for new terrain,” said Berrecloth.

With over 60 years combined experience between them, each athlete brings something unique to the adventure. Simmons with his vast experience, Berrecloth with his wilderness training, Storch with his contagious enthusiasm and McCaul … well, he just wants to catch his first salmon and throw huge tricks. Even the most seasoned athletes saw moments of great trial and resilience on this journey.

Filmed in August 2016 with Canadian production company Freeride Entertainment, this documentary was not only about highlighting a unique downhill experience, but also about showcasing the beauty of Canada’s natural landscape.

With guidance and permission from Yukon Tourism, Champagne First Nations as well as Canadian and American National and Provincial Park officials, all details were considered in order to ensure the preservation of the land and environment.

Shelters were built on elevated structures, flame-retardant blankets were used to eliminate scarring on the ground from camp fires and all waste (including human) was carried out of the camp where it could be disposed of properly. The unique shale and rock sediment of these northern trails left no traces behind, keeping the mountains as pristine as when they were discovered.
