SCOTTSDALE, Ariz. -- Mighty Mud Mania is an annual tradition in Scottsdale.
Hundreds of people are expected at Chaparral Park on Saturday to compete in several obstacle courses.
The event began in 1976 as a promotional gimmick for Shout Spray pre-wash and has become a major event.
Mighty Mud Mania is from 8 a.m. to 2 p.m. on Saturday. Children must be present to register and a signed permission slip is required. Participation is free, but organizers ask that participants bring a non-perishable food item to benefit the Vista del Camino Food Bank.
