SIR 400k--Three Passes
From the SIR website:

Ride Description: An old SIR favorite. We'll start in North Bend and take I-90 over Snoqualmie Pass to Cle Elum. From there we will head to Leavenworth across Blewitt Pass. From Leavenworth, well take US-2 back over Stevens Pass to Sultan. From Sultan, well follow back roads to Monroe, Snohomish, and Lake Stevens. From Lake Stevens, we go back to Snohomish and into the Snoqualmie Valley via Connelly Road and High Bridge Road. Carnation, Fall City, Snoqualmie Falls and FINISH!
