The contestants are not worthy of 100k!!

Most of the contestants are so dumb, its seems that the winners are not worthy of the 100k. I mean there were 2 episodes where a team have quit half way through the show and there are only 3 teams. And in most episodes the winners are so far ahead of the pact there were not much of a competition. There always one team who know how to read and follow instructions and have patience while the other teams just make stupid mistakes and don't follow instructions or even worst can't read maps. And in one episode one team were so unfit they can't finish the challenges and quit.
