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 inclusive. Access and belonging are considered from the start, so runners can arrive prepared, take on a real challenge, and feel part of the day.
