Castle Rock Trail Festival and liveBIG Run

Saturday, October 2, 2021

Welcome to the Town of Castle Rock’s 2021 epic trail event. The Trails Festival is back for its sixth year! Come to challenge yourself on the vast ridgeline trail system and enjoy Castle Rock’s local trails.

Trail run options range from the liveBIG 5K to the Ultra Marathon 50K. If you’ve run this trail system before, you know these are some beautiful and beguiling trails.

Races will begin at 7:30 a.m. near The Amphitheater at Philip S. Miller Park and wind through the single and double-track trails at Philip S. Miller Park and Ridgeline Open Space. You will take in the impressive views of the surrounding buttes and the scenic views of Castle Rock as the trail twists and winds over the flowing race course.
