This will register you for the entire 2024-25 winter run series. Please make sure you only select one Gobble Wobble race unless you have mastered how to be in two places at once.

Series Awards
2024-2025 | 2023-2024 | 2022-2023
Runners must participate in 4 of the races to be eligible for 5K OR 10K series awards. If you run the half marathon, you will be awarded 5 points regardless of placement in the half. You can switch between distances (at no cost) but you must run in at least 4 races of the same distance.
The overall male and female winner for the 5K and 10K series will receive a free entry into the 2024-25 series and series trophy.
Overall age group medals and awards will be distributed at a wrap up event that will be scheduled and announced after the last race in the series.
Series Rules
- To be eligible for the final championship awards, runners must have participated in four of the seven races.
- Awards will be based on a point system (1st place: 10 points, 2nd place: 9 points, 3rd place: 8 points, through 10th place).
- All runners receive one point for finishing regardless of ranking.
- Division winners (5K & 10K) will be allocated 11 points and those points will be added to their age group ranking.
- In the event of a tie, age will be the tie breaker with the oldest individual winning.
- Series points will be calculated on the total points an athlete accumulates in that division.
- In the event no one wins 4 events to be eligible for the overall winner, the individual with the most cumulative points will be the winner. If there is a tie, the oldest runner will be crowned the champion.
- All age groups are based on the age of the runner on 3/24/2025.
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!
Grab three of your friends and create a team. Hey, it's free and you can create the team during registration.
How it works.
☕️ The Famous Hot Chocolate Bar is Back! ❄️🍫
Returning for the 2025–26 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!
