Presenter: Bradley Cooper & Holly Morris

Bradley Cooper has his adventure set out for him by the army on this trip - it's the time of year in West Virginia for kayaking the premiere river in the United States - the Gauley. Every October, the Gauley's dam is released, making it a huge challenge for even the best kayakers. It's known as the Gauley Season and it draws river rafters and kayakers from all over the world for the thrill of experiencing Class IV and V rapids.

In Part Two, Holly Morris has her own physical endurance levels to deal with in part two, as she makes her way by packhorse through the Sangre de Cristo mountains in southern Colorado. After meeting up with a Vietnam vet-turned buffalo rancer, Holly finds that just getting to the snow line isn't enough for our Holly. Even an impending blizzard doesn't deter her as she dons snowshoes and makes the long trek up to Lake Goodwin.
