Tricaecathlonomania (abbr. Tricadecathlon or Trica) is a large-scale scavenger hunt marked by a considerably large list and 24-hour runtime. It was originally created and judged by Alex Robins and Tad Johnson in Northfield, Minnesota in 2001. First located only at Northfield High School, it has quickly grown in popularity and spread to towns and colleges around the United States. Unlike a traditional scavenger hunt, things to find comprise only approximately a quarter of the list along with feats to perform, things to make, and trivia to know.
