This is the 20th year of the Grasshopper Adventure Series. A NorCal original that schools riders on the back roads and trails of Sonoma and Marin.

Watch highlights from Old Caz, a mixed terrain 50 miler with 4500 feet of climbing. This is one event not to miss. The roads, the dirt, the views, and the creek crossing! All adding up to a great adventure.

Here’s to another 20 years!
