Mark your calendars, because this Labor Day weekend we’re bringing the heat with something truly Completely Stupid and Utterly Pointless (CSAUP)—in the best way possible.

On Sunday, August 31, 2025, the men of F3 Naperville and the women of FiA Naperville are teaming up for a one-of-a-kind endurance challenge:

👉 24 Miles in 24 Hours
One mile on the hour, every hour. Starting at 6:00 AM Sunday, Aug 31, and finishing with mile 24 at 5:00 AM Monday, Sept 1.

And because no CSAUP is complete without a strong finish, we’ll roll right into a celebration bootcamp at FiA Fortress / F3 The Complex on Monday morning.

How It Works

• Run it. Walk it. Ruck it. However you move—just show up for your mile.

• Teams or Solo:

  • Go solo if you’re crazy enough 😅

  • Form a squad (max 5 pax per team)

  • Or sign up as a free agent and get matched up

• Each mile, at least one teammate must be out there putting in the work. More? Even better.

• Teams can be a mix of FiA & F3 pax. It’s about community and pushing limits together.

• Enter your FiA/F3 name when you sign up.

What to Expect

• Teamwork: Decide who’s tackling which legs. Share the grind, celebrate the victories.

• Community: FiA and F3 under one banner, side by side, mile after mile.

• Facilities: Bathrooms available overnight at Fortress/The Complex (yes, we’ve got you covered).

• Swag: T-shirt details and pricing coming soon—because you’re going to want to remember this one.

Why Do It?

CSAUP events are about more than mileage. They’re about pushing beyond comfort zones, finding new strength in yourself and your teammates, and building bonds that last far beyond the event. This is a chance to show up, step out, and do something epic alongside your F3 and FiA family.
