Cascade Bicycle Club's site has a collection of ride suggestions, including ones from other Seattle touring bicycle clubs.
This weekend - June 8 - is Cascade's Flying Wheels ride, starts at Marymoor Park. A variety of distances up to about 98.5 for the longest one - look at their site to find out where not to be riding if you don't want to be on the same road with several thousand others.
But, if you don't mind being on the road with them, start in Snohomish. Ride the Old Snohomish-Monroe Road to Monroe, go south through Tualco area, take a right and go west on High Bridge road. Go on west, staying near the river, then north on Springhetti road and back to Snohomish. Then, go west on 1st, and 2nd, under Highway 9, and on to Everett via Riverside, Riverview and Home Acres Road. turn south, head through the Lowell section of Everett and back to Snohomish on the Lowell-river Road. This will be about a 55 mile loop. First part is shared with the Flying Wheels route, the section over to Everett isn't.
