Used in the 1800s to transport gravel for the construction of the western section of the Transcontinental Railroad, the Western Pacific Trail now forms a part of this mostly-flat course where you can haul in a personal best!

All races begin and end at Quarry Lakes. The 10K and half marathon races go out along the Alameda Creek Trail. Trails are primarily dirt fire trails, with sections that include gravel (used by the parks to prevent erosion) and a short paved section.

Hikers/walkers/runners of all levels are always welcome!
