No Boundaries

The aspirants choose their initial leader and encounter a challenge at a river canyon.

In this episode's first challenge, half of the trekkers must search for a dry bag on an island. The leader divides them up into three two-person teams to accomplish the task. Later in the program, one member of the group collapses while on a fishing boat.

The trekkers are divided into two teams as they paddle for five miles in separate canoes toward the Uchuck, a 136-foot World War II minesweeper. Along the way, the boaters must capture three flags to win a group reward.

The participants compete in a kayaking event on the Gold River that requires them to place colored rocks at different points (which are marked by flags) along the rapids. Later, the trekkers board a racing yacht and one member of the group voluntarily jumps overboard into freezing water as part of an event that requires the others to rescue the swimmer in less than eight minutes.

The competitors go fishing on a boat called the East Isle, and are given two hours to catch 500 salmon in order to win a group reward. Later, the trekkers return to the Pacific Ocean for the last time, where they find the kayaks they need.

The participants mountain bike along a 16.5-mile course, then use a raft to transport themselves and their vehicles across the Chilko River to their next destination. Later, they travel down the Chilko on two rafts to retrieve blue and red cards stuck in the water.
