From my doorstep on southside Cougar Mt - about 25-50 miles in length. I stopped driving cars/trucks years ago, enough pollution in the world.

I ride to Issaquah, do around Lake Sam or up to Preston. Those are about 50mi.
South of me I ride Cedar River trail and to Maple Valley, 35-40 miles. Sometimes the back route from Maple Valley, Ravensdale and toward Enumclaw.

I can ride to NBend and may find a motel for a couple of nights for rides from there, before Winter arrives in force.

Thanks for considering my possibilities. I accept my limitations with grace but occasionally with a bit of too much cycling route repetition. Trade-offs, we all choose them.

Couple years back I based out of Crystal Mt Resort for 4 days of rides - possibly too late to plan that this year.
