Special Statement

It is with a heavy heart that we announce the cancellation of this year’s Terrible Two.  

Unfortunately, there is too much uncertainty for us to consider rescheduling the event for later in 2020.

All registrations and merchandise purchases will be transferred to 2021.

Stay safe and thank you for your support and understanding.

We look forward to seeing you all on June 19th 2021!

Please contact ridedirector@srcc.com with any questions or concerns.









The Terrible Two:

Sonoma County's longest running and most challenging timed road cycling event.

The Terrible Two is our region's version of an epic, and has been running strong since 1976.

There are two routes:

There are two challenging routes, neither for the faint of heart. The first, starting at 121 miles is considered a tough century, and a gateway ride to the more formidable Terrible Two 200 mile course. It is a slightly abbreviated version of the Terrible Two and excludes Napa County. It also starts two hours later. Both are equally supported throughout.


Competition and Awards


We are introducing new ways to be competitive in either the 121 or 200 mile routes. Our focus with these new forms of recognition is to improve rider finish rates, and to reward you with the recognition you deserve for tackling one of the country's toughest events.
