Tribal Closures (update July 2022):

When circumnavigating Mt. Adams it is critical to do thorough research on the Yakama Nation Website to check for land closures and to obtain their permit and/or permission before attempting this route.  If the land is closed no one should be on it; we have Flagged prior efforts who were on the tribal land during a time of closure. The tribal land may be closed even when the rest of Mt Adams Wilderness is open.

This is a route along the Olympic Coast that seems logical but has not seen much FKT activity.  Here are some posts from our old website (none of these people identified themselves):

Hello All,

I'm new to this board and poked around a little bit but couldn't find any info on any Olympic Coast runs in WA state.  I pulled off  a 50+ miles in 18 hours along the Olympic Coast in June 2014. From Shi-Shi to Oil City Road, involves beach running, beach head overlands, and timing of the tides... I have GPS documentation and online pre-run announcement.
