The Snowball Series is back for its 45th year in 2025! Join us for the full series while we tour areas of our beautiful city. Can't make it for all the races in the series? Sign up for any of the races individually. The series is designed to encourage you through the coldest months of the year while promoting health, fitness, and fun for people of all ages and abilities. So dress warm, bring some friends, and join our winter running family.

Full series participants receive a custom Snowball Series swag and a finisher medal for each race distance! If you can't make all 4 races in-person, series participants can submit times virtually for weeks they miss and still receive all the medals. *Virtual times cannot earn points for series placement, however.
