Choose from 100 Miles or 100 Kilometers

Course Overview

The 100 mile course is comprised of six full loops on the 15.3 mile Pemberton Trail and a half loop on the Pemberton and Tonto Tank Trails. Trails feature rolling single track through the Sonoran Desert. Run past giant Saguaro Cactus, granite boulders and dry wash-beds as you tour the most popular trail of McDowell Mountain Regional Park. 100 kilometer runners will compete four full loops of the Pemberton Trail.

Loops are run “washing machine” style, meaning each is reversed allowing you to keep an eye on the competition, see your friends and meet other runners all day and night.

Each loop features a gentle 600 foot climb from the start/finish at Javelina Jeadquarters to the high point near the foothills of the McDowell Mountain range. The trail dips in and out of wash beds on the far side of the course before descending back to the start finish. The trail is a mix of hard packed granite, rocks and sand.

Course Markings

The course will be marked with orange ribbon with black polka dots along the entire Pemberton loop.  Green ribbon will be used to mark the Tonto Tank trail for the final partial loop.  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, glow sticks will be placed around the loop to further assist runners. Glow sticks will be placed approximately every quarter mile and at all trail junctions.

Additionally, all trails and trail junctions within McDowell Mountain Park are signed with permanent signs by the park.

Course Description

The race begins at the Pemberton Trailhead and heads south across the dirt parking lot, quickly narrowing onto a mix of sand and gravel covered, rolling single track. The trail crosses McDowell Mountain Park Drive a few hundred meters 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. After dipping in and out of several dry washes, you will reach the second junction with the Tonto Tank Trail (where you will turn on the final seventh loop) and our self-serve water only checkpoint, Tonto Tavern.

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 brand new Pemberton Trail leaving the Jackass aid station which winds parallel to the old Pemberton trail jeep road. This is now a slightly downhill and winding trail that will take you 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 and is only 1.5 miles from Jeadquarters. From here the trail winds its way towards Jeadquarters on a more narrow trail, dipping in and out of a series of sandy washes that are only a couple of feet high.

The final loop follows the Pemberton Trail from Javelina Jeadquarters to Tonto Tavern. Make sure to take the Tonto Tank Trail whiche departs to the right. Take this very nice, rock free trail downhill until it rejoins with the Pemberton Trail. Turn left and run back to the finish line and you are done!
