My very own.... TV show!

I don't really have my own Tv show, but If I had my own TV show, It would go like this:

My Tv show would be called "A Journey with Challenges." 20 people compete to win a million dollars. The 20 people go to 17 different places together and compete in challenges. One by one their journey will end untill their are three people remaining! The three people remaining will compete in one final challenge!
