Run beautiful, technical, and original trail races in the Pacific Northwest.

Terrain, season, and local context shape the course, logistics, and race-day experience. We want every Cielo Running event to feel specific to its setting, not like a race that could happen anywhere.

We believe challenge and welcome belong together. A race can be technical, demanding, and competitive while still being professional, clear, and welcoming. We help runners arrive prepared, take on a real challenge, and enjoy the day.
