How to Register
Registering for the Series
Select the distance you would like to run for the series. If you register for the half marathon, you will automatically be placed in the 10K at races that do not offer a half marathon.
The same applies to 10K runners at the Frosty 5K. Since there is no 10K distance at that event, all 10K series participants will automatically be placed in the 5K.
Registering for the series will sign you up for the entire 2026–27 Chilly Willy Winter Run Series.
Registering for Single Races
Individual race registration will open later in the year. Please check back soon for more information.
Kiddos 1K Registration
As always, kiddos races are free at all Chilly Willy Winter Run Series events. Registration is required, but there is no charge.
Finisher Woodles & Awards
Your 2026-2027 Finisher Woodles!
A medal... made of wood... also known as a Woodle! Every finisher, no matter the distance, will receive one! Each Woodle has a magnet on the back so you can show off your achievements on your fridge.
Crafted by Ridgeway Woodworks, these unique awards are made from reclaimed wood—so they’re not just stylish, they’re also eco-friendly, helping to reduce waste!

Series Awards
2026-2027 5K Series Standings | 2026-2027 10K Series Standings
2025-2026 | 2024-2025 | 2023-2024 | 2022-2023
Runners may switch between the 5K and 10K at no cost. The 5K and 10K series are scored separately. To qualify for awards in either series, runners must complete at least four races at that same distance. All seven race results count toward series points.
The half marathon is not scored as a separate series event. Participants whose results are entered in the 10K event will earn points in the 10K series.
The overall male and female winners of each series—the 5K and the 10K—will receive a series trophy and free entry into the 2027–2028 series.
Age-group medals and awards will be presented at a wrap-up event. The date will be announced after the final race.
Series Rules
- To qualify for 5K or 10K series awards, runners must complete at least four of the seven races at that distance.
- Points are awarded at each race: 1st place receives 10 points, 2nd receives 9, continuing through 10th place, which receives 1 point.
- Every finisher receives at least 1 point.
- Points from all seven races count toward each runner’s series total.
- Ties are broken in favor of the older runner.
- If no runner completes four races at a distance, the runner with the highest cumulative points in that series will be the champion. If there is a tie, the older runner wins.
- Age groups are based on the runner’s age on March 21, 2027.
Walkers Welcome!
We’re thrilled to offer a walker division as part of the Wisconsin Chilly Willy Series! Whether you're walking for fun, fitness, or competition, we encourage you to join us and enjoy the race at your own pace. To ensure a smooth and enjoyable experience for all participants, we kindly ask that walkers stay to the right side of the road. This allows runners to pass safely on the left and helps maintain a steady flow throughout the course.
Thank you for being part of the Chilly Willy community—we can’t wait to see you at the starting line!
🏃♂️ Team Challenge: Run Local, Win Local 🏆
Introducing the Chilly Willy Running Team Challenge — part of our commitment to supporting the Run Local / Buy Local movement!
Our goal? To shine a spotlight on:
👟 Local race organizers (that’s us!)
🛍️ Local running stores (that’s where you shop!)
💪 Local running teams (that’s YOU!)
It’s a fun and competitive way to build team spirit, support the local running community, and make winter racing even more awesome. Rally your squad and get ready to run together, cheer each other on, and maybe even take home some team bragging rights!

☕️ The Famous Hot Chocolate Bar is Back! ❄️🍫
Returning for the 2026–27 Chilly Willy Winter Run Series—it's everyone's favorite post-race tradition: the Hot Chocolate Bar!
After you cross the finish line, warm up with friends at our delicious hot chocolate station, loaded with a huge selection of sweet toppings and mix-ins to create your perfect cup. It’s the ultimate reward after a frosty run! You'll find our Hot Chocolate Bar at every Chilly Willy Series race.
🏅 We’ll also be announcing awards post-race—and there's no better way to celebrate than with a cup of cocoa in hand! The hot chocolate bar is definitely the place to be after the race.
Come for the run, stay for the chocolate! 🍫☕️
The Mother Nature Factor
Sometimes, Mother Nature has her own race plan. While we strive to ensure every course is measured accurately, real-world factors can occasionally impact the exact distance.
From dead-end roads to unexpected highway crossings, wandering cows, or good ol’ Wisconsin snowstorms, things happen. We promise to do our best to keep the course as accurate as possible—but if it’s a little off, now you know why.
Thanks for rolling with it—just part of the adventure! 🏃♀️❄️
Average Joe & Jane Awards
The Average Joe & Jane Awards are back for the Chilly Willy Series 5K Runs are are presented to the male and female runner who finished in the exact middle of all runners. Winners will receive a t-shirt and custom medal!
