For the return part of my West Coast trip I'm thinking of perhaps trying the Sierra Cascades route. Sounds interesting and perhaps I could link up with it north of SF. and take it back up north of Seattle. Better than riding some highway, but depends how hilly it is. Gotta be some big ones up there and after doing the coast I might be tired. I'm also not so young anymore. Anyone done that route yet? What are the gradients like?I will know in 6 weeks or so since we start it this Friday.
Looking at the maps it looks pretty tough, especially for the part south of the Yosemite area. It looks tough enough that I am nervous about starting in the south with my pitiful amount of mileage for the year.
That said you should be fairly road hardened by the time you get there and heading over from Sand Francisco you will miss the southern part which is probably the hardest part.
You could use the Western Express to connect to the Sierra Cascades.
