Childish Nonsense

Palatine, United States • 25 Apr 2026

Event overview

Childish Nonsense is a trail running event held in Palatine, IL, at Deer Grove Forest Preserve west. The event offers four distance options: 50 miles, 50K, 25K, and 10K. The organizer is CUSS Running, which describes itself as a group that adds whimsy to training and race calendars.

Course and logistics

The course is mostly a wide trail with little technical terrain. Runners complete multiple laps depending on distance: the 10K is one lap plus extra, 25K is three laps, 50K is six laps, and 50 miles is nine laps. One aid station is located at the start/finish and is on course about every 5.5 miles. Personal crews may set up only at the start/finish area. 50-mile entrants may use a pacer after four loops. The cutoff time for all distances is 8:00 PM. The organizer also notes there will be informal activities described as "shenanigans" throughout the day.
