NBCUniversal International Formats has sold “Spartan: Ultimate Team Challenge” to Denmark’s Kanal 5 after launching sales at Mipcom.

Commissioned by Kanal 5, the Danish adaptation will be produced by Nordisk Denmark and will mark the first international adaptation of the NBC game show.

Based on the Spartan Race brand, “Spartan: Ultimate Team Challenge” features elite athletes, teams of friends, families and co-workers who work together as they race across Spartan obstacle courses to test their endurance and ultimately win a cash prize.

The game show premiered on NBC in June and rated as the second most popular program on its timeslot and as one of this season’s top three new unscripted series.

Yvonne Pilkington, SVP of format sales and production for NBCUniversal International Formats said “Spartan: Ultimate Team Challenge” combined “the scale of an epic sporting spectacle with entertaining and inspirational reality story-telling.”

Pilkington pointed the program has “attracted a substantial US audience but has garnered interest from buyers across the globe.”

Anne Garlichs, head of local programming at Discovery Networks Denmark, called the program “America’s most hardcore TV shows.”

“On Kanal 5, we have a clear ambition to have the best TV programmes in action-packed entertainment, factual and crime. With a combination of physical strength, teamwork and obstacles, the show is a perfect fit for Kanal 5’s brand and DNA,” said Garlichs.

The Danish adaptation will bow on Kanal 5 next Spring.

NBCUniversal International Formats is currently in advanced talks in two major European territories.
