About the event
The ČSOB Winter Series turns the cold months into an active running season through four events from December to March. What began as winter preparation for the spring marathon has built a strong tradition of its own, reaching its 16th edition in 2026. Each edition has its own theme — the St. Nicholas Run, the Epiphany Run, the Valentine's Run and the Women's Day Run. Thanks to a flexible race format, you can choose a classic run at selected locations or a virtual version anywhere in the world. It's an ideal way to stay motivated, stay connected with the community, and keep your race fitness through the winter.
