Race Info

Cordova is surrounded by extraordinary ecosystems that combine to form one of the world’s most spectacular natural environments and host to a thriving wild salmon migration. We now host participants from all over the world, and in one of Alaska’s most beautiful and friendliest communities. We have welcomed runners from Japan, Australia, Brazil, Norway, and several states in the continental U.S.A such as New York and Florida – plus many more. Some people come back year after year, and we hope that you will do the same. Our salmon runs are dedicated to the five species of salmon native to our area. Source
