About this race
The River Run returns for its 6th year. This family-friendly event offers a unique experience meandering through a working sand and gravel quarry. See the quarry site, the banks of the San Benito River, and rock-processing equipment, all surrounded by natural scenery. Options are available for individuals or families, with special pricing for groups of four or more. The Graniterock River Run supports the YMCA of San Benito County.
