Fancy Nonsense 25k/50k

Race Update

Due to major trail renovations and closures at Palos Forest Preserves from August to December we will be moving this race to Deer Grove Forest Preserve for the 2026 event!

A Nonsensical Running Experience

Due to construction at Palos Forest Preserve, this race will be moving to Deer Grove Forest Preserve for one year only, in 2026. This fall, picture single track wrapped in gold, amber, and deep red, crisp air, and just the right amount of crunch underfoot. It's the kind of course that makes you forget you're racing at all. The course is designed to give you space to return to the joy of running. Yes, you will accomplish your goal distance. More importantly, you will smile, you will laugh, you may even be a little confused. You will test your mental and physical limits while having a blast. This is a grassroots race, through and through. No frills, no fuss, just good trails, good people, and a community that shows up for each other. Bring your kids, bring your dog (on a leash), bring your best friend who's never run further than a 5k. Everyone belongs out here. Cash Prizes We're offering prize money this year for top finishers in the men's, women's, and non-binary divisions: 1st place: $400 2nd place: $200 3rd place: $100 Aid stations will be stocked with your typical ultra fare, plus a few surprises, because that's just how we do things. The course will wind you on mostly single track, and cut off time for both races is 5pm. Register by Sept. 15th for a guaranteed shirt.

CUSS Running

Our goal is to build a community that creates a space for the individual to fall in love with the magic of running. Mission To help others fall in love with ultrarunning. Vision To make you & the world slightly better through laughter & pain.

BIPOC & LGBTQ+ Entries

One of the things we strive for is to create inclusion and equality in the running community. As much as we want to say that all you need to run is a pair of shoes, we know the reality is much more complex. To create intentional space for people, we have a number of free entries for our races that we would like to extend to BIPOC and LGBTQ+ athletes. We would like to emphasize that these are not need based or scholarships. These entries are an affirmation of belonging in our community. We are not in any way publicly advertising who accepts an entry, and you do not have to be an out member of the LGBTQ+ community to receive one. We are not questioning or asking for additional information from anyone who asks for a code, they will be handed out as long as we have funding to do so. If you would like a code, please email us at [email protected] . We have earmarked funds for both BIPOC and LGBTQ+. Please feel free to share this offer with friends.

Entrance Policy for Transgender Athletes

Entrance Policy for Non-Binary Athletes

People whose gender is not male or female; including but not limited to: genderqueer, agender, bigender. We want to acknowledge, respect, and provide opportunity in the registration process to express their desired pronouns.
