Chilly Willy Winter Run Series - SEVEN Events!
The Chilly Willy Winter Run Series runs from November 7, 2026 to March 20, 2027 in Wisconsin and is produced by Silver Circle Sports Events, LLC. The series is centered in Oconomowoc, WI (1327 Wall Street) and comprises seven events held at multiple local venues.
The series features multiple distance options and event types:
- 5K races at most events
- 10K races at most events
- Half marathon offered at two events
- Walk series
- Ruck 5K
- Free kids 1K at all events
Registering for the series signs a participant up for the entire 2026–27 series. Participants who select the half marathon are automatically entered into the 10K at races without a half distance; similarly, 10K series participants will be entered in the 5K when a 10K is not offered.
Awards are given to overall, age group, and team series champions. To be eligible for final championship awards, runners must compete in at least four of the seven races. Series scoring uses a point system with higher points for top placings and one point for finishing. Every finisher receives a wooden finisher award with a magnet produced by Ridgeway Woodworks. Additional features noted in the series include a CW All Access Pass option, a hot chocolate bar at each race, and a walker division with a requested right-side course position.
