Please suggest some stories that have characters -- who as regular people, not trained athletes -- are involved with risky feats of endurance for profit.
Fiction can be any form: movies, books, short stories, graphic novels, etc.
Here are some examples of endurance "crazes" from the past: walking long distances (hundreds of miles), treading water in swimming pools (80+ hours with no rest), marathon dance-offs (that would last weeks), fasting (for months at a time), etc.
In the 1970's, I remember there were events where contestants had to keep both hands on a new car without rest. It typically took place in a store or busy parking lot. The last person who had their hands on the car would win it as a prize. This type of thing would go on for weeks, with people being hospitalized due to exhaustion or heart attacks.
Anyway, can you suggest some fictional stories that involve characters participating in these "endurance for profit" games?
For instance, They Shoot Horses, Don't They?
involved characters desperate to win a marathon dance-off during the 1930's. Kafka's A Hunger Artist
involves a man who fasts himself to death as part of a vaudeville act.
Dystopian or futuristic settings are okay, but I am looking for situations where characters VOLUNTEER to become involved (even if out of desperation) because they want to win a prize. Not looking for stories where someone is forced or coerced into participating to avoid being killed or tortured. If the character's motivation is borderline, please post your suggestion anyway but leave a caveat.
Thanks in advance for any answers. It is much appreciated!
