I'm looking for the name of an old show

About eight years ago or so, there was a cable tv show on which the host took his guests (1-2 people who were family/friends) on an outdoor adventure. Often the trips that they took were to national parks. The guests were challenged by their trip. However, is was NOT a survival show. I would swear on the proverbial stack of bibles that the show was on the Livestrong tv network. However, I wrote to Livestrong.com, and the editor didn't know anything about a tv channel, much less a show. So, now my questions are: 1. What was the name of the show? 2. Did Livestrong (either Livestrong.com or Livestrong.org/foundation) have a cable tv network? Please help me---I need some sleep!
