About the Event

The California Gold Rush Trail Run (Spring) is an endurance event scheduled for Saturday, April 25, 2026, within the Marshall Gold Discovery State Historic Park in Coloma, California. This historic location marks the site where James W. Marshall first discovered gold in 1848. The race features a diverse range of distances, from a half marathon to a mile and a kids' run, all set against the backdrop of the Sierra Nevada foothills and the South Fork of the American River. The terrain consists of a blend of scenic single-track dirt trails and occasional paved sections, incorporating technical switchbacks, rolling hills, and flat river-side stretches.

Coloma is located in El Dorado County, approximately 40 miles northeast of Sacramento. Geographically, the area is characterized by rugged river canyon terrain and Mediterranean-climate vegetation, such as oak woodlands and chaparral. In late April, the climate in the foothills often involves significant diurnal temperature shifts; average morning lows can be a chilly 6°C (43°F), while daytime highs typically reach 22°C (72°F). The park's proximity to the river can contribute to damp or foggy mornings, though the race proceeds rain or shine. Runners are cautioned to prepare for cold early starts and technical footing on the trail ascents.

The event is organized by Troy's California Trail Runs and emphasizes the intersection of athletic performance and California history. Due to the nature of the single-track trails and technical sections, strollers are prohibited for safety reasons. All participants must finish within the 4.5-hour time limit. The race serves as a gateway to the larger regional trail system, offering views of wildlife and the historic preservation sites of the gold discovery era. Registration remains open until the day of the event, though early entry is encouraged for logistical planning. Course maps and specific aid station information are updated periodically on the official TCT Runs website.
