Childish Nonsense

Childish Nonsense is a multi-distance trail event held at Deer Grove Forest Preserve west in Palatine, IL. The course is mostly a wide path and is described as not technically difficult. The route is run in repeated laps.

There is one aid station located at the start and finish area, which participants encounter roughly every 5.5 miles. No other crew access is available on the course; crew may set up only at the start and finish area. Runners in the longest distance may use a pacer after completing four laps.

Distances offered include:

  • 10K
  • 25K
  • 50K
  • 50 Mile

The event description also notes planned playful activities during the day described as shenanigans to encourage a lighthearted atmosphere.
