Hidden among the glaciers on Axel Heiberg Island, high in the Arctic Circle, are mountain bike lines too incredible to ignore. Harsh temperatures, volatile weather and nine-month winters mean the area is normally devoid of human life. But each summer, this frozen landscape flourishes under endless daylight, revealing a spectacular ecosystem. Join Darren Berrecloth, Carson Storch, Cam Zink and Tom Van Steenbergen in North of Nightfall as they embark on an expedition to the top of the world to explore this relatively unknown land. Here they discover a rapidly changing environment steeped in history along with ground-breaking descents unlike anything anyone’s ridden to date.
