About the Event
Join us in the scenic Santa Rita foothills for short and long advanced courses! For those looking to choose their own adventure, the Wildcat Explorer course incorporates all controls from the advanced courses, as well as several beginner-friendly options. The terrain is quite runnable, with only a few Catclaw patches that are easily avoided. Although every effort was made to minimize fence crossings, you may encounter barbed wire fences once or twice, depending on your chosen route. Cattle may be present—please do not harass them.
