Courses
All courses feature a wide variety of typical desert trail running surfaces including crushed granite single track, rocks, boulders, sandy washes, old jeep roads, dry wash beds, and even cross country terrain. Be prepared for a wide variety of conditions from very well defined, well kept trails to remote old game paths on the Pedersen Trail (50K & 31K only) traveled by few park visitors. There are a couple miles of the Gadsden Trail through a dry wash in the 19K, 31K and 50K races. There are also several miles of soft sandy wash/road on the Pederson Trail Loop in the 50K/31K. Be prepared to trek over boulders and through deep sand and gravel!

Course Markings
Each course will be well marked with orange plastic ribbons with black polka dots. Trail junctions and turns will be well marked with colorful laminated signs. Please pay attention to these signs at each junction as there are multiple race distances and race courses! Course signs will correspond with your bib color (All races = Orange, 4M = Blue, 19K = Green, 31K = Yellow, 50K = Pink). In addition, blue & white checkerboard plastic flagging will be hung along with “WRONG WAY” signs to designate non-race trails. All runners are responsible for understanding the layout of the courses. Please familiarize yourself with the course maps on our website prior to race day and/or print a map to bring along with you.
Parking / Start Area
The start/finish line is located at the Rodeo Arena. Once you enter the park through the entry station, follow Casey Abbott Drive North past the Turf Picnic Area. The road will curve south and turn into 143rd Drive. Continue until the road turns to Arena Drive. We will be setup by the Rainbow Valley Trail Head. This is approximately a 5 minute drive after entering the park. Detailed park map
Camping
Estrella Mountain Regional Park offers seven RV sites. Each site has a large parking area to accommodate up to a 45′ RV and is a “Developed Site,” with water and electrical hook-ups, a picnic table and a barbecue fire ring. Group camping is permitted for up to two nights. Motor home and RV clubs can reserve a group ramada, and park in nearby parking lots. Electricity is provided at the ramadas for small appliances, such as coffeepots and radios, but do not provide enough amperage for motor home or RV hookup. All sites in the campground are available on a first-come, first-served basis.
