About Cielo Running

Cielo Running organizes beautiful, technical, and original trail races in the Pacific Northwest. Each course is designed around its terrain, season, and trail access, with clear communication, prepared volunteers, and well-supported aid stations.

We take race operations and stewardship seriously. That means respecting the trails and the people who maintain them, while considering access and inclusion in how we welcome runners, hire, select providers, and work with community partners.
