The Cave Creek Thriller features a challenging 50K route that connects two regional parks in a single race. It kicks off at the Agua Fria Trailhead near Lake Pleasant, guiding participants along the scenic Maricopa Trail and a brief segment of the Black Canyon Trail. Runners will traverse through desert corridors, climb past Spear S Ranch, and ultimately enter Cave Creek Regional Park, finishing their journey along the picturesque Go John, Quartz, and Overton Trails, making it a unique and rewarding experience.
