Timely Nonsense : Chicago, IL

Timely Nonsense is a timed running event held in a 58 acre city park at 2741 W. Montrose in Chicago. Runners complete repeated laps on an approximately 1 mile paved loop path within the park.

Available formats include:

  • 12 hour individual
  • 12 hour 4 person relay
  • 6 hour individual
  • 3 hour

There will be one aid station at the start and finish area stocked with typical ultrarunning foods. A vendor on site will offer additional ultra-style snacks. Team options include two person and four person relays.

An hourly element called the Nonsense gives a new challenge at the top of each hour that participants must complete during that hour. The event is presented by the Curious Ultrarunner’s Secret Society, which describes its mission as helping others fall in love with ultrarunning and its vision as improving participants and the world through laughter and pain.

The organizers note a registration deadline in early September and a separate August deadline for guaranteed shirt size. The event includes provisions to increase inclusion: a limited number of free entries are set aside for BIPOC & LGBTQ+ athletes, recipients are not publicly identified, and the organizers accept an entrant’s declared gender without additional documentation. For non binary entrants, organizers will amend registration records on request when the registration platform lacks the option to record pronouns.
