Build my planThe North Olympic Discovery Marathon, Marathon Walk, Marathon Relay and Half Marathon take place on a unique point to point course that incorporates the beautiful Olympic Discovery Trail with stunning views of the Olympic Mountains and a five mile finishing stretch along the shores of the Strait of Juan de Fuca. The 10K, 5K and Kids Marathon are an out-and-back along the shores of the Strait of Juan de Fuca.
Frequent sightings of seals, eagles, and an array of shore birds are common from the trail. Iconic trestle bridges provide beautiful back drops. Salmon can be seen spawning at the Morse Creek crossing in the fall. The North Olympic Discovery Marathon is truly one of the most beautiful marathon venues anywhere.
This rails to trails course is a wide, hard surface (99% paved) trail. The course is marked at every mile and water stations are located approximately every two miles. Cool June weather can be expected – average high is 65F, average low is 49F, average mean is 57F.
The race is organized by the Port Angeles Marathon Association – a group of accomplished amateur athletes.
The Marathon is a USATF certified course and a Boston Marathon qualifier.
