Event Description

Cosumnes Crusher

The Cosumnes Crusher will blend three awesome bike riding disciplines into one race – gravel grinding, cyclocross and sweet singletrack in Rancho Murieta.

The race will traverse 38 miles of beautiful historic countryside including sections of the original gravel road route between Sutter’s Fort and Sutter’s Mill and singletrack-repurposed hydraulic mining flumes twisting through oak woodlands and over rolling green hills splashed with spring wildflower color.

Littered throughout the final stage of the race will be cyclocross obstacles including steep hill scampers, riverside sand traps, beer barrel crawls, and wooden hurdles keeping racers’ hearts pinned.
