Gold Rush Adventure Challenge: Dawn to Dusk

The Gold Rush Adventure Challenge: Dawn to Dusk is a 12 hour adventure race based in Sausalito, California. Participants navigate through the Marin Headlands, the San Francisco Bay, and Angel Island. The course covers approximately 50 miles and includes multiple disciplines.

The event consists of:

  • Trekking
  • Mountain Biking
  • Paddling

Teams ranging from solo participants to groups of four move between checkpoints using only a map and compass, as GPS devices are not permitted. The terrain includes steep coastal ridges, ocean cliffs, and historic military sites, offering views of the Golden Gate Bridge and the San Francisco skyline.

A central transition area located in Sausalito serves as the race headquarters. Teams return to this station between different legs of the race to change gear and adjust their strategy. Each team decides their own route to collect checkpoints within the 12 hour time limit. The race is open to individuals and teams, with registrations available for solo racers or groups of two, three, or four people. Discounted entry fees are provided for participants under the age of 25. Visit the organization's website for the most recent information.
