Out Olympian Gus Kenworthy Embarks On "Ultimate Expedition"

The hunky freeskier has a peak to reach.

Has freeskier Gus Kenworthy met his biggest challenge ever?

The Olympic silver medalist is competing on Ultimate Expedition, a new adventure reality series where eight celebrities attempt to summit Mount Tocllaraju, one of the highest and most dangerous peaks in the Peruvian Andes. None of the competitors have had previous climbing experience.

Hosted by YouTube adventurer Jukka Hildén, the 10-episode YouTube Red series also stars UFC champion Chuck Liddell and Jackass comedian Steve-O, plus YouTubers Chachi Gonzales, JusReign, Lia “SSSniperwolf” Shelesh, Nikki Baker, and Furious Pete.

"Mount Tocllaraju is not the only mountain the cast is trying to conquer," reads an official synopsis. "Each climber has a personal challenge they are hoping to summit as well. Some are chasing dreams, some are redefining themselves, and some are looking for a spiritual awakening during this once-in-a-lifetime experience."

Kenworthy, who is dating actor Matthew Wilkas, came out publicly as gay in a 2015 ESPN interview.

Ultimate Expedition premieres January 17, 2018 on YouTube Red.
