The biggest food eating competition is Nathan's Famous 4th of July Hot Dog Eating Contest. They have 13 qualifier contests in the preceding 2 months. But I tried to sign up for one about a month ago, and discovered that they are by invitation only!
I emailed someone in the company, and was told that all the contests were booked up, and I could only get on the waiting list. It seems to me that they ought to be able to accommodate anyone who wants to enter the contest. Is there some shortage of hot dogs?
Whoever wins is not really the champ. He will only have beaten those who were allowed to compete.
