Ridgeline Rampage

April 29, 2017

Castle Rock


This unique, 16-mile racecourse linking the Miller Athletic Complex and the Ridgeline Open Space Trail System is a one-of-a-kind, phenomenal way to kick off the season in style.

We’ll have plenty of aid stations, treats and hydration around the course to keep you fueled.  Awards and after-party will be on the grassy lawn at the finish line!

Come race with us on April 29, 2017 at this beautiful new venue. In addition to the race, there will be activities for spectators, kids and families with hula-hoops, beach balls, badminton, food truck and more!

New this year – We are offering FREE Junior racing for ages 10-18. That’s right, just pre-register on-line for a FREE Junior entry, or sign up on race day for only $10 bucks!
