Presented by Silver Circle Sports Events, LLC

Bundle up and lace up—Old Man Winter is ready to race! ❄️ Join us for the 2026–27 Wisconsin Chilly Willy Winter Run Series, where chilly temps meet hot competition across seven exciting events. This beloved winter series is your chance to embrace the frost, stay active all season, and have a blast doing it!

Whether you're racing solo or forming a team, there's a distance for everyone:

• 5K and 10K options at most events
  
  
• Two half marathons included in the series
  (Participants who choose the half marathon option will be automatically entered into the 10K category for events that do not offer the half distance.)

• 🚀 Skip the Lines With The CW All Access Pass! 🏃‍♂️

  CW All Access Pass?
  Your ticket to skipping the packet pickup line and heading straight to the start line! 

  How It Works:
  ✔ Register for the series in any distance 🏅
  ✔ Opt out of a shirt and save $10 👕💰- this automatically gets you the pass
  ✔ Receive a reusable ankle strap for timing ⏱️ 
  ✔ No check-in required – just show up and run! 🏃‍♂️🚀

  More running, less waiting—because race day should be running, not the lines. 🌲

  🏅 Awards will be presented to overall, age group, and team series champions.

Don’t miss your chance to experience Wisconsin winter running at its best. Run one race—or run them all. Either way, we’ll see you at the start line!
