the stoke races

Roxborough 50 Mile

The course opens in the red rock formations of Roxborough State Park before climbing steadily into the quieter, more exposed terrain of Pike National Forest. From there, the race settles into its true character — a long, sustained out-and-back on the Colorado Trail that rewards patience, rhythm, and restraint.

This is not a course of tricks or manufactured difficulty. The challenge comes from continuity: long runnable sections, stretches of technical footing, and enough elevation and exposure to demand respect without overwhelming the experience. Success here comes from pacing, presence, and the ability to stay steady when the miles stop feeling novel.

The Roxborough 50 Mile is for runners who value grit over glory — those who earn their hardest days one steady step at a time.

Technical Details

• Distance: 50.2 miles

• Elevation Gain: 9,337 feet

• Terrain: Predominantly singletrack with sections of forest service road. Long exposures and sustained climbs.

Roxborough 50K

The Roxborough 50K offers the same philosophy as the 50 Mile — distilled into a sharper, more compact test.

Beginning among the red rock outcroppings of Roxborough State Park, the course climbs into Pike National Forest transitioning into the Indian Creek area. The route emphasizes flow and consistency, asking runners to manage effort across sustained climbs, runnable stretches, and technical sections that reward focus over force.

This is a 50K for runners who want a course that feels earned. There’s no filler and no distraction — just a clean line through varied terrain that encourages smart pacing and honest execution from start to finish.

Technical Details

• Distance: 31.1 miles

• Elevation Gain: 5,279 feet

• Terrain: Technical singletrack, sandstone technical features, and rolling montane valleys.

• Execution: Fully supported with aid at optimal locations and a flowing descent to the finish.

Stewardship

This race exists because of trust.

Roxborough Ultras is the first event ever permitted to host a trail race within Roxborough State Park. That opportunity is not something we take lightly. We are deeply grateful to Roxborough State Park, the U.S. Forest Service, and Douglas County Open Space for their partnership, guidance, and confidence in our ability to steward this landscape responsibly.

Every aspect of this event — from course design to runner experience — is shaped by that responsibility. The routes are intentional, the footprint is minimized, and the emphasis is on respect: for the land, for the agencies that protect it, and for the runners who show up prepared to meet it on its own terms.

Beyond race day, we plan to host trail work days in coordination with park and forest service teams as a way to give back to the places that make these events possible. Stewardship here is ongoing, not symbolic.

This race is not about spectacle. It’s about earning the right to be here, doing the work the right way, and leaving the place better than we found it.

The rox ultras phoenix

A symbol for the hard stretches — the miles where it stops being fun and turns into work. The phoenix is grit earned in effort, not borrowed from hype: the quiet choice to stay present, stay steady, and keep moving.
