Gold Rush Adventure Challenge: Dawn to Dusk - September 19, 2026
The Gold Rush Adventure Challenge: Dawn to Dusk is a USARA-sanctioned, 12 hour adventure race based in Sausalito, California. Teams navigate by map and compass only; GPS devices are not permitted. The course crosses the Marin Headlands, the waters of San Francisco Bay, and Angel Island, and features coastal ridges, cliffs, and historic sites with views of the Golden Gate Bridge and San Francisco.
Teams may consist of 1 to 4 racers. Participants will alternate between trekking, mountain biking, and paddling while choosing checkpoints to collect within the time limit; each checkpoint is worth points. A central transition area in Sausalito allows teams to change gear, regroup, and refuel between disciplines. There are no aid stations on course; teams prepare food and supplies in a transition area bin or bag.
Distances vary with route choices but the course roughly includes:
- Paddle: ~6 miles (boats provided)
- Mountain bike: ~30 miles
- Trek / run: ~14 miles
Racers must bring required equipment such as a mountain bike and helmet; local bike rentals are available. All boats are provided and personal boats are not allowed. A full mandatory gear list and final race details are supplied before the event. Navigation and teamwork are integral parts of the format.
