JP's Backyard Ultra/Hike, The Final Edition

Join us for JP’s Backyard Ultra, a one-of-a-kind ultramarathon and hike set in the scenic trails of Skyline Wilderness Park in Napa, CA. Now in its fourth and final year, this grassroots event is more than just a race, it’s a celebration of life, resilience, and community.

Born from my personal journey with Stage IV mediastinal paraganglioma, JP’s Backyard Ultra is a fundraiser for the Pheo Para Alliance, a 501(c)(3) nonprofit (EIN 26-1510652) dedicated to empowering patients, families, and medical professionals affected by pheochromocytoma and paraganglioma through education, advocacy, and global support. Learn more at www.pheopara.org.

Whether you're in it for one loop or ten, come run or hike in solidarity, to honor those facing rare diseases, to challenge yourself, and to stand as part of a growing force for good.
