Such an inspirational challenge and for a great cause!

**Gold Rush | 13×13 is a 13-day endurance project celebrating the natural diversity of California.** From April 20th to May 2nd, 2026, Seth Wilmoth will run 13 marathon-distance routes across each of California’s EPA Level III ecoregions — from redwood forests to high desert basins to coastal mountains.

This project is rooted in a lifelong connection to California’s landscapes and the belief in the power of outdoor spaces to inspire, restore, and bring people together.

All donations raised here support **California State Parks Foundation**, helping protect and expand access to California’s state parks through trail restoration, habitat conservation, youth programs, and community stewardship initiatives.

Thank you for being part of this journey and supporting the public lands that make projects like this possible.
