The summary for season 1:

In one of the toughest competition shows ever attempted, eight teams of elite athletes embark on a harrowing journey across the unforgiving Alaskan wilderness. However, with no food or shelter, they must fend for themselves and survive off the unwelcoming land. Over the course of six different race legs, 46 days, and 300 square miles, teams will traverse through some of the harshest and most extraordinary landscapes in the world, from sprawling mountain ranges to massive prehistoric glaciers and never-ending suffocating rainforests.

It’s a challenge. People like challenges. It’s not like you’re watching someone being tortured
