Lace up your shoes and grab your cold weather gear because Old Man Winter is knocking at your door looking for a running partner. Join Silver Circle for the 2024-25 Wisconsin's Chilly Willy Winter Run Series. All SEVEN races are back this year and you'll have plenty of opportunity to race in everyone's favorite time of the year - winter! Race the series as an individual or grab some friends and race as a team. All races have a 5K and 10K option, and two races have the option for a half marathon distance (series runners who select the half marathon distance will automatically be dropped to the 10K distance for races without a half marathon distance). Awards will be given to the overall age group and team series winners.
