Trail Run at Ridgeline Open Space in Castle Rock

Lace up and get ready for a scenic and energizing trail run through Ridgeline Open Space, one of Castle Rock’s local gems! This area features four interconnected loops that total about 9 miles of rolling singletrack—perfect for runners who love variety, views, and a bit of a challenge.

Our route will combine several trails to explore most of the open space, winding through hills, grasslands, and rocky terrain. The hilly sections make for a fun but tough workout, and with plenty of route options, we can adjust the distance as group—go shorter, go longer, or find the perfect in-between.

Trail Details:

• Distance: 3 to 9 miles (adjustable based on group preference)
• Difficulty: Moderate
• Terrain: Rolling hills, dirt trails, and beautiful views of Castle Rock
• Highlights: Flexible route, great workout, and wide-open scenery
• Bring: Water, sun protection, and your running shoes with good traction

Trail Guides: Anne Sevilla and Robin Kelly
