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! The marathon course is now USATF-certified and can be used to qualify for races like the Boston Marathon!
Hikers/walkers/runners of all levels are always welcome!

Trails are primarily dirt fire trails, with sections that include gravel (used by the parks to prevent erosion) and a short paved section. Hills are nearly non-existent, so bring on the speed!All participants can receive a copy of their appropriate course map on race day. Each course will be marked with ribbons, flour and signs to help keep runners on the correct course. Volunteers will also be on the course at key locations to help direct runners.
