The Eau de Hell will not qualify you for RAAM. In order to use a brevet, it must be a full 1200km, you must state your intentions to use it as a qualifier beforehand, and you must finish in the required time (varies by age, but much less than the full 90 hours). The closest one to you will be the Cascade 1200 in Seattle (

The RAAM organisers are also open to requests from riders who did not compete in a recognized qualifier, but believe they have equivalent results.
