Limestone Canyon offers runners the experience of seeing “original California” in all its glory. The course will meander under a canopy of thick oaks, alongside seasonal creeks, a year-round dripping spring and past a striking geological formation known as “the Sinks.” This pristine canyon will give runners a sense of calm solitude as they race through serene meadows and rolling hills. Once on the ridge you will be captivated by panoramic views of the Pacific Ocean, Catalina Island, Irvine Lake, and the Cleveland National Forest.
