Course and logistics

All races begin and end at Quarry Lakes. The 10K and half marathon routes run out along the Alameda Creek Trail. The course is described as mostly flat and uses the Western Pacific Trail, which was used in the 1800s to transport gravel for construction of the western section of the Transcontinental Railroad. Trails are primarily dirt fire trails, with sections of gravel used for erosion control and a short paved section. The event offers bib pick-up, shirts and awards, free event photos, published results, and volunteer opportunities. Sponsors include GU.
