The October 17 event will combine three challenging Sierra foothills courses with fundraising for local youth mental health programs.
NEVADA CITY, Calif. — Forested climbs, quiet backroads and sweeping views will greet riders when the Heart of Gold Gravel Race returns to Nevada County on October 17.
The sixth annual event offers approximately 28-, 47- and 74-mile routes through the Sierra foothills. Each course includes substantial climbing and long stretches of gravel, while fully stocked aid stations provide riders with strategic opportunities to rest and refuel. Organizers have also added an e-bike category for the short and medium routes this year.

Race founder Hardy Bullock developed the event around some of his favorite roads and trails, including those along the Yuba River corridor and San Juan Ridge.
“I ride all over, but my favorite spots are the famed trails and roads of Nevada County—especially the Yuba River corridor and San Juan Ridge,” Bullock said. “Fifteen years ago, I started this ride to push riders’ limits, blending tight, hamlet-style climbs with wide-open dirt roads. Just when your legs need a break, you’ll be greeted by a sweeping vista, a flat respite, or a fully stocked aid station.”

Heart of Gold grew from “300 Miles for Mentoring,” an endurance ride Bullock started more than 15 years ago to raise money for local youth mentoring programs. The current race continues that mission by supporting organizations that provide mentoring, advocacy, therapy and wellness services to young people in Nevada County.
Since its 2021 debut, Heart of Gold has drawn hundreds of cyclists to the area. The combination of secluded roads, wooded climbs, high-quality gravel and expansive views has helped establish the race as a late-season destination for riders looking for either a shorter outing or a demanding endurance challenge.
“Heart of Gold is about much more than the ride,” said Nicole McNeely, executive director of Child Advocates of Nevada County. “Every rider who crosses the starting line is helping ensure local youth have access to mentors, advocates, therapy, and programs that strengthen mental health and wellness. Together, we’re building a healthier future for the next generation.”
All three routes start and finish at Pioneer Park, 425 Nimrod St. in Nevada City. After the racing, the park will host a community celebration from noon to 4 p.m. with food, beverages and opportunities for riders, spectators and community members to gather.
Proceeds benefit Child Advocates of Nevada County, Bright Futures for Youth, Youth Bicyclists of Nevada County and Heart of Gold Teen Therapy.
The event welcomes riders of all ages. Registration is available at heartofgoldgravel.com.
