ATRA race member Feature this race

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! In addition to the marathon distance, half marathon, 10K and 5K races will also take place.
