Salary of Participation in Extreme Sports
Though extreme sports usually have rewards or pay, real extreme sports are mostly done for no salary at all. A more accurate title would be "Reasons of Participation".
Cheese rolling rewards the Double Glousester cheese that was rolled down the hill if the race is won, and mildly publicized sports such as parasailing have rewards in competitions.
Though there are some awards for classic extreme sports, there is usually not an award at all, except for the sheer joy of participation.
