Skybreaker Racing was founded in 2019 by ultrarunner and adventurer Ben Mitchell along with Yuba Gold 50K. Having grown up in Nevada City, CA, Ben’s intent was to create an event showcasing the beautiful South Fork of the Yuba River.

“We chase the rivers, the mountains, and the soul inside.
We are without limits – we would break ourselves to touch the sky.”
