The course will be marked with orange ribbon with black polka dots along the entire course. Blue & white checkerboard ribbon will be placed at junctions or trails not a part of the race. Bright yellow signs labeled with the Javelina Jundred logo and arrows will also be placed at all junctions on the course, with wrong way signs on trails that are not a part of the race.
During the night, reflective markers will be placed around the loop to further assist runners.
Additionally, all trails and trail junctions within McDowell Mountain Park are signed with permanent signs by the park.
The race begins at the Four Peaks Staging Area (Javelina Jeadquarters) and heads down the Shallmo wash. The trail crosses McDowell Mountain Park Drive a little bit later and continues with more undulating hills. In the next mile, the trail crosses several very sandy areas including Pemberton Wash.
Continuing past the Tonto Tank Trail junction and the sandy area, the trail makes a sharp turn to the left at the base of long hill. A short while later, the trail curves to the right and begins to ascend the hill. You will see the Coyote Camp aid station at the junction with a park service road on the left. The next couple of miles are a steady climb up very rocky trail. There are large rocks embedded in the trail and smaller rocks loosely covering the trail. The rocks soon subside and the trail evens out as it turns north approaching the McDowell Mountains. The hills and valleys become more significant at this point.
The next section of trail dips in and out of even larger sandy washes and desert drainages as the trail continues to head north. There will be many times where you lose and gain anywhere from 20 to 50 feet of elevation. The trail here is a bit narrow and there are some round logs placed in the trail to prevent erosion which you must run over, but it is mostly clear of the rocks present in the first section.
You will wind through the desert and around some neat boulder formations before dropping down near Granite Tank, the location of the Jackass Junction Aid Station. From there, you will take the newly re-aligned (2013) Pemberton Trail leaving the Jackass aid station which winds parallel to the old Pemberton trail jeep road. This section is a gradually downhill single track that winds to the next aid station located at the North road crossing.
The Rattlesnake Ranch Aid Station (sponsored by Surprise Running Club) is located on the south side of the road crossing. From here the first loop takes you along the Escondido trail back to Javelina Jeadquarters. The other loops will take have you continue along the Pemberton trail to the Cinch trail which will take you to Javelina Jeadquarters.
