Technical gold rush singletrack through Malakoff Diggins and the South Yuba River canyon
Other trail races within 61 miles
The flagship distance of the Yuba Gold Trail Runs threads through the heart of California gold rush country. Starting from historic North Bloomfield, the course descends the technical Humbug Trail past ventilation shafts from the Malakoff Diggins hydraulic mining era, follows Humbug Creek to the South Fork Yuba River, then winds along the forested singletrack of South Yuba Trail before grinding up Missouri Bar Trail and a series of Tahoe National Forest fire roads back to the finish. With 6,000 feet of gain and technical terrain throughout, it lives up to its motto: not your mama's trail race.
