The first mile is mostly flat, but there are some rocky sections just stepping over or around and some water crossings. Only running hard after a storm, they are typically not wide or deep and are usually dry in mid- to late-summer.

The run begins through a fairly flat rock garden creek, a bumpy and twisty 1-mile section with intermittent tree cover, but nothing extremely difficult. The trail consists of mostly doubletrack but narrows to singletrack in various spots along the rock garden.

At the end of the rock garden, the doubletrack takes a sharp right turn to begin a 6.2-mile climb. The climb is not extremely difficult, but it is steady with a very small number of flat areas and short descents along the way. A majority of the run does not contain any tree cover.

At 3.3 miles, there is a plateau with amazing views of the San Gabriel Valley and south towards Orange County. It is a popular rest point before the climb gets a bit steeper.

From the rest point, the trail continues to climb as it winds along various sides of the mountains, providing great scenery. The trail ends at a turnaround point with a gate that leads to a dirt parking lot, adjacent to Glendora Mountain Road.

Always keep an eye out for bikers, this is a popular downhill trail for mountain bikers. A good supply of water is also recommended.

Poison Oak is along the trail most of the way, it is wide enough to avoid the plants easily though. There is also cactus in the area.
