Childish Nonsense - April 24, 2027

Childish Nonsense is an ultrarunning event held in Palatine, IL at Deer Grove Forest Preserve west and organized by Cussing Runner. The event offers multiple distances run on a looped trail; the course surface is mostly a wide path with little technical terrain.

Distances include:

  • 50 Miler
  • 50K
  • 25K
  • 5.5 Miler

Runners complete laps of the loop: 5.5 milers run one lap, 25K runners complete three laps, 50K runners complete six laps, and 50 milers complete nine laps. There is a single aid station located at the start/finish, which runners encounter approximately every 5.5 miles. Outside crew access is limited to the start/finish area. Fifty-mile entrants may use a pacer after four laps. The cutoff time for all distances is 7pm.

The organizer describes the event atmosphere as playful, with planned shenanigans during the day intended to evoke a sense of childhood fun. The organizing group, CUSS Running, states a mission to add whimsy to ultrarunning and to build community. The event includes intentional inclusion measures: free entry codes are available for BIPOC and LGBTQ+ athletes as an affirmation of belonging, codes are distributed while funding allows, and entrants may register under their declared gender. The organizer will amend records on request for non-binary entrants as needed. Visit the organization's website for the most recent information.
