Limestone Canyon offers runners the experience of seeing “original California” in its fall glory. Meandering through the serene meadows and rolling hills runners experience the calm solitude of this pristine canyon. The 12k and the 25k include a new trail called “Dripping Springs”. Both courses have sections of steep inclines and fast descents. Loma Ridge and Limestone Ridge will captivate you with panoramic views of Pacific Ocean, Catalina Island, Irvine Lake, and the Cleveland National Forest. We take pride in giving you the best bang for your buck. Shirts, Medals, Post race refreshments, overall and age group awards, and a raffle!
