Sebastopol, California


2024 Event

It is with deep disappointment that we announce the cancellation of the highly anticipated Terrible Two endurance road cycling event, originally slated for June 15, 2024. This decision affects not only the renowned Terrible Two double century, but also the Terrific Two double metric, and the Tremendous Super Century.

For over 45 years, the Terrible Two has stood as a pinnacle of challenge and camaraderie in American road cycling. Understandably, this decision was not taken lightly, but with the prospect of registration numbers missing our minimum threshold for 2024, we ultimately decided to uphold the legacy of the Terrible Two and will be moving to an every-other-year format.

We understand that this news may come as a disappointment, and we sincerely apologize for any inconvenience caused. Information regarding refunds for entry fees will be communicated to all registrants promptly.
